ghetdjc320 Posted August 17, 2021 Share Posted August 17, 2021 Anyone have a diagram for the switch pinouts and wiring for a diy harness build for power locks and windows? Planning on installing oem power locks and windows in my 91. I know @Minuit has a lot of good info on the topic and I’m sure others do as well. I’ll be building the harness myself so any detailed info would be great. Link to comment Share on other sites More sharing options...

eaglescout526 Posted August 17, 2021 Share Posted August 17, 2021 For having down just power locks, all I can say is, get a enough length of wire, set up the system outside of the truck to ensure you have it all wired right and I recommend OEM connectors but you can choose which ever you like.

If you have some oem connectors that would be great otherwise I’m using weatherpack connectors and possibly soldering the pins for the switches. Not sure but any input would be great. If someone has a 2dr xj cross cab wiring harness from a 91 with power locks and windows that would be fantastic Link to comment Share on other sites More sharing options...
eaglescout526 Posted August 17, 2021 Share Posted August 17, 2021 Weather pack should be just as good if not better than the metri-packs. Now the lock solenoid is its own connector and I’m not sure if that connector is around or not but it might be. I haven’t had to look for that one specifically.

Minuit Posted August 17, 2021 Share Posted August 17, 2021 The cross cab harness can come from a 91-92, possibly 93 4-door too. Mine did, and the only way you can tell is that there's an extra connector behind the passenger kick panel. The back half is not necessary for it to work. The factory harness makes this swap "a drunk baby can do it" levels of easy. From there, keyless entry is a snap too. Power is provided from the fusebox via a fusebox insert and a circuit breaker for each system. As far as I know, all of these harnesses are pre-wired for power mirrors too, and adding that functionality is a simple matter of adding the switch, plugging in the fuse tap, and mirrors. This post on my build thread is the one where I performed the swap. If 4-door door harnesses are being used, there will be a large and a small connector at the driver door switch. If you're using a 2-door switch pack, two wires need to be switched from the small connector to the large connector, at which point the small connector can be cut out. If you are using older switch packs and the power locks act up when you plug both switches in, you need to bend up a ground tab on the driver side switch pack.

watchamakalit Posted August 17, 2021 Share Posted August 17, 2021 The lock solenoid connectors are the same for all 4 doors on the xj. Just throwing it out there for a rebuildable source. Link to comment Share on other sites More sharing options...
