I did a retro fit of rear Electic windows a few weeks ago on my new project. If I get some time I'm going to do a post on all of the wring required and how it all goes together . It was fairly easy to do if you are a competent DIYer. I had a complete loom from a donor A2 so could work out what cables go where. I spent a day separating out the cables and had spare cable to make this work it’s a really sticky job removing 20 year old loom tape This is not a step by step how to but to get some pointers if you want to do this yourself
The B pillar connectors are the same as the front A pillar connectors. For wiring the only pins you’ll have to remove from the existing B pillar connectors are the speaker pins and move them over to the new donor connector as this is what I did . I got a tool to depin on eBay ~£6 . Don’t try with out a good depin tool I left the original cables on the factory connector as they were there so could revert back at any time by swapping back manual doors. Adding the speaker pins was the last job and I added Bose at the same time a complete loom end to end. If you can get a set of front A pillar connectors with some loom it will make adding these a lot easier as all of the pins are what’s needed for the rears and extend the cables. It also allows you to do bits in stages so you don’t have no locks on the rear doors whilst you switch over. I did mine over a few days as I had time to stop and start as needed. I took the seats out as well as I had more room to work
I’ll put some details of where are good places to get Kline left and right side power and negative connections making up the looms will take some time and getting the lengths correct so not much is hanging about as well as suitable cable
Connector pic (new style) this is from the passenger front side so you can see what’s what
The 2 red orange that are crimped they go to either fuse 39 for the right side and 41 for the left side . I ran mine to the fuse box but these can be taken from other places
Thick red and black stripe goes to the blow fuse in the passenger A pillar. I added a new blow fuse as there is a slot under the cradle for it to go you need to run a cable over from the drivers side as well . Then connected this to the main live bundle
Thick brown there are a few places you can connect to passenger and drivers side a pillars crimp and connect
Can hi and can low . orange and green and orange brown. I run these to the passenger foot well where the cccu is as they are part of that bus. I’ll need to look at the plug on where on the ccu it goes. You’ll need the drivers side to get over as well . There are lots of other places you can get connections for ease of work there is lots of space to work here
Red and grey stripe is Kline again this is on the cccu in the passenger foot well. You need cables from both sides I can’t remember the plug will have to check later
The hard part is dismantling the doors and replacing the frames and the looms for the rear motors. These looms would have come from the donor vehicle . There are guides on here how to do that part and it’s a fairly complete guide and some details on cabling . I had full doors wrong colour so could test before I did the swap.
I get disconnected the connector for manual rear doors on the ccu so could revert back if needed.
You also need to code the cccu for rear electric windows vcds is needed for this. Then the remotes need coding too .
For most this is a big job and a non starter and Tom would be your best option if you’re not confident doing this yourself.
