From what i know there is a 3sge adapter harness that you can get to make it a 3sgte. (all plug and play). i think i even noticed it in the parts section of this site b4? not sure though. $400 does seem like a lot to pay for wireing. but if it comes back as pressure 2 says ....then it is worth it. i did my own harness with the diagrams that mike made. (i had to pay for the diagrams and promise not to resell it) Now, i found some things on my harness that were different than what mike had in the diagrams... and had to figure out another way to wire it up. Plus i took the alternator wires and all mian wires from my 5s harness and completely re-ran them in the 3s harness to avoid splicing major power wires!!!!
If any of you guys plan on doing it yourself it will take you 3 days to do it! full weekend job.
I am not the kind of person to give away all of mikes secrets for wireing, but if you guys have problems i will try to help you figure it out!
