A friend has a forest green Caravan, 1996. It's manual everything. She has kids and a business and it's a pain to use the key all the time.

I feel a little bad, because she said she wanted a cheap van, and I found her this one for $900 with only 120,000 miles. It passed a safety, my mechanics asked to buy it from the seller if she wasn't going to 'cause it was in great shape. But then she just keeps spending whatever her mechanics say needs doing, she's probably spend more than $5000 on it in the two years she's owned it. So this is like a $1500 van she's spent $5000 on. Ugh. And it's still a POS powerless baseline van. It was supposed to be a "$1000, drive it until it dies, fix nothing, buy another one when it dies" van. She's put like 60,000 miles on it (lots of city-to-city driving for business) so there's no point in having something nicer when she'll mile it out in 5 or 6 years anyway.

I also have a 3rd gen Caravan (with dual sliders and more options), so I figured I at last had some knowledge of how to fix little things.

Anyway, I feel bad for suggesting she buy it if she's the kind to be scared by mechanics and dump money (might as well have bought a $3000 van in that case), so I have started going to junkyards and yanking doors from 3rd gen power Caravans, to at least get her a less useless van for how much she's put into it.

My goal is: Power windows, power locks, power popouts.

So far I have:
- Replaced the liftgate (swapped the handle/lock to her original)
- Replaced the sliding door (only a single, sadly).
- Replaced the driver's door.
- Grabbed popout actuators.

There was also body damage to these doors, so, it was a beautification as well (or I might have just added solenoids).


Okay, now my problem...

My mechanic skills are mostly at the "unbolt part-shaped thing, replace" level. I'd never touch an engine, but I can swap doors.

I had looked into the hinge area of the driver's door and saw it had the receiving plug for the power door, so I (falsely, spoiler alert) presumed that at least that much of the wiring harness was universal. Well after I've finally gone and swapped the entire door and then swapped back the handle mechanism... I see that the matching hinge electric connector only has 5 pins filled, versus how all the 20 (? ish) pins are in use on the power door.

My intermediate goal was "do no harm", and I figured even if the other doors weren't wired yet, or if I had to wire them manually, I'd at least get the driver's door under power. So, 20-ish wires, nope. But, despite having at least 5 wires (I'm not sure why, her original door had nothing plugged into it so they all would have dead-ended in the hinge plug, why not zero wires?)... none of them actuate the door locks or window. So now she can't even open her window.

So I'm kind of stumped. I was prepared to just pop up body panels and snake my own wiring for the other doors if need be, but I figured the driver's would at least work.

Any suggestions?

Also, does anyone have a pinout of that hinge plug, and/or the multi-switch panel in the driver's door (all windows up/down, lock unlock, pop-out windows L/R)? That'd save me a ton of time on my multimeter.

Anyone done this before or know of a thread where someone did?

Is there going to be a vacant fuse/relay I'll need to fill to make this work perhaps?

I feel like I'm 80% done but burning out when the end was in sight.

Thanks all!

 

Just a light bump for attention.

Specifically, if anyone could link a wiring diagram or pinouts on that door plug, that would be much appreciated.
