Hello everyone! I know it can get old answering silly questions from people but I really could use some love from Tesla owners!

I have a drivers side power seat from a 2018 Model S.

I am attempting to wire the seat up to power and install into my Sim Racing Rig. The seat has several different larger wires that have unusual colors doe power and ground wires. I am not sure which is which and I am afraid to test it as it may short something out in the MSM Memory Service Module.

I have searched and searched for anyone else who may have posted the pin outs ormwiring diagram for this model seat but can’t locate anything. The closest thing I found was one for a 2014 seat but the wires and color codes don’t match up.


Anyone with any advice or info would be greatly appreciated. Normally its Easy to identivy power ‘ ground wires as they are usually a larger gauge wire. There are only 4 large wires in the entire wiring harness. One is all white, one is orange and green, one is all yellow, the other is green and black. Common sense tells me that one of these wires is the power wire and another is ground I just don’t know how to identity which is which without a diagram. Any ideas please shoot them my way!

I’m not sure if I’m able to help you, but I do have all kinds of information on the wiring and connectors of the Model S. Problem is that there are a lot of differences between left-hand drive - rear wheel drive, right-hand drive - dual motor, etc. all the info combined is +/- 1,5GB so we need to agree on how to share these files. Send me a PM. Happy to help
