Hello Matt, I can’t seem to find the switches themselves; the Ford dealer here can’t find anything even tho I give him the option code. He is stuck in a loop of my van wasn’t equipped with it- I know, that why I want it! My searches aren’t much better. Could you provide a link please

Matt. Thanks so much for the reply. I’ve been reading a lot about batteries and charging batteries and even though this simple set up would work I’ve decided I may be compromising the life of my battery in doing it. So I am going to bite the bullet and get an inverter/charger , a smart B2B charger, and a automatic charger relay. The solar set up will have to wait. I think we will do portable panels because of the kayaks. I will use your posts as guidance and I thank you so much for sharing information. The more I learn, the more I see what I don’t know.

In reply to Rich.

Do I need more than that one CCP?

No, it just limits the amount of current you can take from the van electrical system.

I know it’s not optimal but the alternator will charge my house batteries, right? I can add all the right stuff later. I can connect my house battery red lead to that CCP and the black to a ground or even to the van battery’s negative post. I will break the red lead with an on/ off switch.

Technically this would probably work. But at a minimum I would use one of these https://amzn.to/2xN28TI so you don’t kill your starter battery inadvertently.

Matt, first off thank you for all the great information. My wife and I are building our traveling home from a used 2016 Ford Transit 250 cargo van. The electric is what has had me the most perplexed. I have two 100AH AGM batteries that I want to charge from the 150 amp alternator in my van. I thought it was as simple as hooking up to the van battery with an isolater on/off switch to separate the van and house batteries when we were camping somewhere. The enormous amount of posts and videos of others doing their builds and living their dreams is astounding. I was addicted for weeks watching and soaking in everyone’s ideas. What I learned real fast is that the house electrical system IS NOT that simple. I had no idea that different batteries had different charging criteria for optimal performance. Automatic charging relays,battery to battery chargers, smart chargers, sine inverters, charge controllers. Etc etc Wow my head was spinning. Your Electrical System Build Guide was great !!!!!!!!! It taught me so much of how to do this right. I ran out to the van and looked on the door side of my drivers seat. And there it was. I never noticed that before. I pulled off the cover and found the CCP. I took off the front seat, removed the battery and found the place where 3 fused CCP s would be. Wow! How did you know to look there? I only have one 60 amp fuse. Probably because I have the one battery model instead of the 2 battery model. So here is my thinking. Do I need more than that one CCP? I know it’s not optimal but the alternator will charge my house batteries, right? I can add all the right stuff later. I can connect my house battery red lead to that CCP and the black to a ground or even to the van battery’s negative post. I will break the red lead with an on/ off switch. I will add all the other stuff later but I want to get this build done in November so we can do this bucket list trip now. The rest of the build is easy for me. What’s my hurry? One of us is growing tumors every year. Oncologist says it can’t be stopped. As long as she can survive the surgery and as long as it grows in a place they can do something , we can keep on going. Tumor markers are already detected. We expect a surgery in the spring. So we would like to travel the west in our van now. In the spring after surgery I will complete the electrical build and she will need time to recover again. Then we will be off again. We are both very fit, we travel with bikes and kayaks and to do as much of this while we still can. So if you can let me know if my thinking is correct and I am not going to fry my batteries, I would love the assurance or even words of wisdom saying NO don’t do that. Rich

In reply to Eric. On the 2016 Transit the connection is under the drivers seat. See the pictures in this blog post.

Does anyone know where the connector is located on the 2016 Transit. Also is the it the same pigtail in both locations?

Thanks,

Eric

I haven’t had a problem with the switches since I haven’t used them. I did plug the harness for the switches with the four wires into the connector behind the dash, right of the glove box. I didn’t plug the other multi wire harness in since I have no need for those circuits. I just assumed the 4 wire connector was for the Aux, switches and did not test them.
Could be I was wrong and there not for the switches. It would have been nice if Ford provided info with the wiring kit.

Have my conversion completed and just finished a 900 mile trip, averaged 20 mpg with onboard computer and by actual gallons used, both within a few tenths. 150, 3.5, w/3.31 rear, med roof 130 wb.

So far I’m very impressed with my Transit.

In reply to Matt. Thank you for the reply. Yes, I have a FORD Field Service Engineer looking at the problem and even he is confused about where they put the outputs. I think they moved all outputs for the switches to the 42 pin connector behind the glove box. But I don't want to strip and test 42 different wires. I was hoping they would have released another service bulletin by now.
