As far as wire harnesses; the answer is maybe maybe not, it depends on what was on hand in the factory, evidently.

 

Well that certainly is interesting! I didn't happen to look at the seats in the junk yard to see how they plugged in this past weekend... but I did notice that there is a plug sticking up out of the carpet under the seat on the drivers side of my car when I was vacuuming it out (possibly the first time ever it had been vacuumed).

So, if it was not wired for the power seat from the factory, would it have a loose rectangular plug under the drivers seat?

Could someone post up a pic of the plug on a power seat?

Thanks for all the info!

I have a 08 LS panel. I have installed electric seats. The wires were there just had to plug them in.

 

I don't have one, so don't know exactly what these mean. My guess is the large one is the main harness and the other 2 are seat and back.
