yeah, like I said above.....it just says to hook all 6 wires from the passenger's side up to the like wires on the driver's side and the only two wires that NEED to be hooke up to your HEEP are the power and ground. Then the yelllow wire CAN be hooked up to your PCI.
I just hooked up the red/blue and black wires from the passenger's side straight up to the battery and had full function of all three motors. I put the seat on there to make sure it would have full range of motion. It's going to be tight, but it's going to work
Bringing your thread back from the dead. I installed WJ seats into my XJ recently, and was able to wire the passenger side seat up no problem. However the drivers side won't seem to work. I am using red and black wires as 12v power and ground but no luck. I was thinking possibly a bad recline seat switch or worst case scenario the motor. Also do you happen to know the wires used for the lumbar support?
No clue man. I actually just sold my front WJ seats a few months ago after having them sit around for a few years. I never got around to installing them, figured I wouldn't, and think I'm going to go the suspension seat route eventually. Good luck!
Revival of a dead thread, but has anyone successfully rewired the factory WJ seat heaters to be used in the XJ?
I know the WJ heaters have their flaws, and I know it is possible to add after market heaters. I was speaking to my father-in-law who is an Electrical Engineer, he felt pretty confident it would be possible to make a simple adapter to make everything play together nicely. He fabricates stuff like this frequently, and sells them to anyone interested typically, so if anyone has wiring diagrams for these seats, maybe we can make this mod a little more fruitful.
I am hoping a close to plug-n-play adapter can be made using the WJ harness, heater switch(s), "a magic box" and some leads for a power source.
That link does have some good info, especially for wire coloring. It however does not have everything we need to know. There are 4 wires for the seat heaters, has anyone figured out which each one does?
I have heard conflicting statements about how the temp is regulated. Some threads say there is thermistors, which if that was true they would pretty much self regulate. Some threads say there is a thermometer built i to the pad which then the control board uses to regulate. The second scenario makes more sense as to why there would be 4 wires. Instead of 2 or 3.
After doing a fair amount of making up diagrams and looking for hardware it seem to be like most people are saying, just get aftermarket seat heaters. It turns out that the seats I picked up did not have heaters anyways, which made my decision for me. It would be possible to use the seat heaters, but you would need: Relay, DC converter, heat sink, voltage regulator or programmable current limiter, and a switch. There is a more shade tree way of putting some in line voltage limiters which would heat up themselves, but is a little suspect. I am not sure if it would be possible to contact one of the seat companies, like Rostra, and ask for a new complete wiring loom. The hardware for the seats was going to be about $45-65 per seat, I was able to get aftermarket seat heaters for both front seats for $50 total shipped. Still pretty cheap considering its a much more comfortable seat, leather, has power recline and lumbar, adjustable head rest, and now heaters. Plus, that map pocket in the back of the seat is actually pretty handy since the XJs do not have much for cubby storage.
Sorry if this wasnt the solution we were hoping for, but at least its not overly expensive either.
