If you’re building a Ford Transit camper van, one of the more useful Ford-specific features to understand is the Transit Customer Connection Points. Ford provides an easy method to connect a house electrical system to the vehicle battery system, and in Ford-speak that is a Customer Connection Point, or CCP.
The CCPs are one of the reasons the Transit can be a very builder-friendly van for camper conversions. They provide a straightforward way to connect DC-DC chargers to your Transit, but the details matter. Older vans, newer vans, single battery vans, two vehicle battery vans, and vans with the two alternators are not all the same.
This post is not trying to duplicate Ford’s order option documentation, and it is definitely not a substitute for reading the Body & Equipment Mounting Manual, or BEMM, for your model year. But if you’re trying to understand Transit CCP1, CCP2, and the Dual Alternator option at a practical level, here is a quick take.
What Are Ford Transit Customer Connection Points?
Ford provides an easy method to connect a house electrical system to the vehicle battery system, and in Ford-speak that is a Customer Connection Point. The CCP(s) are located on the outside of the driver’s seat pedestal facing the door. The CCP(s) are an ideal way to connect DC-DC chargers to your Transit.
Older or single battery vans may have a single 60 Amp CCP1, while newer models with the Dual AGM Batteries or Auxiliary Fuse Panel options have CCP1 as well as a 175 Amp CCP2. The CCPs are fused, and accessing those fuses is pretty annoying since they are located in the pedestal underneath the driver’s seat. Because you have to remove the seat to access the pedestal, we highly recommend designing your electrical usage of the CCPs lower than those fuse values.
That is one of the practical points that matters most. Yes, the fuse values set an upper ceiling. No, that does not mean you should design your system right at those limits.
CCP1 vs CCP2
CCP1 is always-on, and CCP2 is controlled intelligently on and off by the van’s computer. CCP2 may be load shed during periods of heavy alternator derating due to heat. CCP2 is not always on, and CCP2 typically remains on for some duration after the engine is turned off.
If you’re comparing CCP1 and CCP2 for a camper van electrical build, the short version is that CCP1 is simpler and lower-capacity, while CCP2 is the more useful interface for higher-power charging setups when the van is equipped for it.
In practical terms, CCP1 may be enough for a more modest electrical build. CCP2 is where things get more interesting if you want more charging power from the alternator while driving or idling.
Which Transit Vans Have CCP1 and CCP2?
Older or single battery vans may have only CCP1. Newer models with the Dual AGM Batteries or Auxiliary Fuse Panel options have CCP1 as well as CCP2. We think that the Dual AGM Batteries option is important for more than one reason, but one of the big ones is that it provides the CCP2 capability that allows a higher-current interface for DC-DC chargers.
Older Transits with specific options may even have CCP3, where all three CCPs are fused at 60 Amps.
That means if you’re shopping for a Transit specifically with camper van electrical in mind, it is worth paying attention to the order options and what Customer Connection Points are present - not just whether it has nice lifestyle features like swivel seats or an extended range gas tank.
Using DC-DC Chargers with a Ford Transit
A Victron Energy Orion XS 50 (or XS 1400 for 24 Volt systems) is a great fit for CCP1 or CCP2. Using one of these chargers provides 50 Amps of charging power from your alternator to your house system.
If you have CCP2 without the Dual Alternator option, then you have more alternator capacity for even higher charging power. Ford alternator sizing has increased over the years, and the 250 Amp alternator is standard in the 2020+ models. Using that 250 Amp alternator as an example, roughly 100 Amps of charging power while driving (less at idle) is available for your house battery bank. Manufacturers recommend using no more than 50% of the rated alternator value, and you need to reserve power for the vehicle’s own use, so 100 Amps from a 250 Amp alternator is a reasonable value.
Two Orion XS DC-DC chargers in parallel or one Sterling 120 Amp DC-DC battery charger are a great fit for CCP2.
This is one place where the Transit can support a pretty capable camper van electrical setup without getting too exotic. If your power needs are moderate, the CCP approach can be a very good way to go.
When installing a DC-DC charger in a Transit, you may wonder where's the CCP ground? The CCP(s) rely on a chassis ground, and those grounds are NOT on the driver's seat pedestal near the CCPs. It's important to identify where you'll make your chassis ground connection early in the build. The BEMM details grounding points in the Transit, but many DIYers use the threaded holes from the D-rings that come with the Ford Cargo Tie-Down Hooks order option.
Is the Ford Transit Dual Alternator Option Worth It?
The Dual Alternator option, which requires the Dual AGM Batteries option and has CCP2, adds a second alternator that works in conjunction with the primary alternator to dramatically increase power at idle as well as reduce alternator heating and loading while the engine is running.
More than 150 Amps of power at idle is available from CCP2 with the Dual Alternator option. Technically, 220 Amps of power while driving (or more) may be possible, but that requires wiring around CCP2 directly to the vehicle batteries as well as participating in Ford’s signaling for load shedding. Interfacing directly to CCP2 and staying below that 175 Amp threshold is the easy way, but you can read the BEMM and make things complicated if that extra charging power is important.
That is really the tradeoff. The Dual Alternator option can be very attractive if idle charging performance matters to you. But if your system is modest, or if you do not need even-higher power aftermarket secondary alternator charging, Dual Alternator may be the right middle ground for high-enough charging rates with a straightforward DC-DC install.
When an Aftermarket Secondary Alternator May Be Better
If even more massive charging power is a need for your system, you should avoid the Dual Alternator option and add a separate secondary alternator kit. With a secondary alternator kit, you can still use a DC-DC charger on the primary alternator in parallel with the secondary alternator regulator, so the kit allows much more charging power as compared to the Ford Dual Alternator option. For example with a 12 Volt 280XP secondary alternator kit and one or two Orion XS 50 DC-DC chargers connected to CCP2, well over 300 Amps of charging power can be expected.
For some camper van builders, this is probably beyond what is necessary. But for higher-demand systems, it is worth knowing that the factory Dual Alternator option is not the final word in Transit charging capability.
Victron vs Sterling for Transit Charging
If you have CCP2, this is one area where Victron DC-DC chargers are a little lacking. Right now, you need multiple Victron Orion XS chargers in parallel to take advantage of that 150+ Amps of easily accessible charging power. Sterling offers a one-box solution to fully use the benefits of the dual alternators, but Sterling does not have any integration to the Victron Cerbo GX and touch screen interface if that is important to your system.
So the decision is not just about maximum charging output. It can also come down to ecosystem preference, monitoring, and how cleanly you want everything integrated into the rest of your electrical system.
Don’t Ignore the Engine Run Signal
Victron and Sterling DC-DC chargers have smart alternator sensing modes so that the chargers turn off when the engine is not running. Especially when using CCP1 which is always on, we highly recommend using Ford’s Vehicle Interface Connector (C33) Engine Run signal to the DC-DC charger’s remote terminal to ensure that the charger never depletes your vehicle battery bank. Read the BEMM for specifics on using the C33 interface signals.
That is a small detail that can matter a lot in the real world. Even when a device has a smart sensing mode, hardwiring the proper Engine Run signal is the safer and more deliberate way to make sure your charger behaves the way you intend.
Final Thoughts
Ford Transit CCP1 and CCP2 provide a pretty builder-friendly way to connect a camper van electrical system to the vehicle side of the van. Older or simpler vans may only have CCP1. Vans with the Dual AGM Batteries or Auxiliary Fuse Panel option can also have CCP2, which opens the door to higher-current charging setups. Add the Dual Alternator option, and the Transit becomes even more capable for high-output charging, especially at idle.
That does not mean every Transit builder needs CCP2 or two alternators. But if you’re planning a larger electrical system and want to make smart decisions before buying or building, these details are worth understanding early.
And as always, read the BEMM for your specific model year before you cut, wire, drill, or assume anything.
Frequently Asked Questions
What are CCP1 and CCP2 on a Ford Transit?
CCP stands for Customer Connection Point. Ford provides these connection points as an easier way to interface with the van’s battery system. In a camper van build, they are commonly used to connect DC-DC chargers to the vehicle side of the electrical system.
What is the difference between CCP1 and CCP2?
CCP1 is a lower-capacity connection point and is always on. CCP2 is higher-capacity and is controlled by the van’s computer. In practical terms, CCP1 can work well for simple, small charging setups, while CCP2 is the more useful option for higher-output camper van electrical systems.
Which Ford Transit vans have CCP2?
Older or single-battery vans may have only CCP1. Newer vans with the Dual AGM Batteries or Auxiliary Fuse Panel options can have both CCP1 and CCP2. If higher-current charging matters to your build, these are options worth paying attention to before you buy the van.
Can I use a DC-DC charger with CCP1 or CCP2?
Yes. Both CCP1 and CCP2 can be used with DC-DC chargers. A Victron Orion XS 50 is a strong fit for either one. If your Transit has CCP2, it gives you more room for larger charging setups than CCP1 does.
CCP1 and CCP2 can be used simultaneously to different devices, but you should NOT connect CCP1 and CCP2 together.
Is the Ford Transit Dual Alternator option worth it for a camper van?
It can be, especially if idle charging performance matters to you. The Dual Alternator option adds a second alternator that increases available charging power at idle and helps reduce alternator loading while the engine is running. For higher-demand electrical systems, that can be a meaningful advantage.
Should I design my system right up to the CCP fuse limits?
No. The CCPs are fused, but those fuses are not especially convenient to access. You must design your system below those fuse limits rather than treating the fuse rating as your target operating point.
Is Victron or Sterling better for a Ford Transit charging setup?
That depends on your priorities. Victron is a very good fit if you want consistency with the broader Victron ecosystem and monitoring tools. Sterling can be attractive if you want a one-box higher-amperage solution, especially for taking fuller advantage of CCP2. The better choice depends on your system goals, not just the charger specs alone.
Should I use Ford’s C33 Engine Run signal?
Yes, especially if you are using CCP1. Because CCP1 is always on, wiring the C33 Engine Run signal to the charger’s remote terminals is a smart way to ensure the charger does not deplete your vehicle battery bank. Even if your charger has smart sensing features, using the proper Engine Run signal is a more deliberate approach.
