I would search out some forums or groups for your make and model camper for upfitter documents. Many times, Ford, GM, Chrysler will put out upfitter documents for those who buy their trucks as a cab and chassis only and other chassis modified units. Think like tow trucks, ambulances, police...etc. These documents will give info on these cool add ons that may not be used in normal production models.

These upfitter documents my list part numbers and other info on interfacing to factory wiring harnesses. They may even make a harness with blunt ends all ready to go or at least give you a part number to reference to.

Back when I had my Silverado, I found tons of PDF's on the GM website for modifiers and upfitters. I had to find them on GM's commercial vehicle website. I have a 46 mb PDF with all the electrical diagrams and connectors used on the truck. You may want to poke around the manufacture's website for your van. Also look to see if they have a commercial vehicle section.

Subject: [K3CAL] Need some molex pins

I've found some auxiliary power switches on my dashboard connected to this large white connector by my side sliding door on the campervan. One is powered with the key on, the other all the time. Perfect place to pick up some power and send to PowerPole outlets nearby. I don't know how these Molex pins are sized to order. Does anyone have an assortment I could get 4 or 6 pins from? And a crimper to borrow for a day? Or how do I order the pins? Plan to put a switched power meter there also.

Thanks and 73
