TII swaps are covered in the FAQ. Don't bother trying to swap an S4 engine into an S5 car. The wiring and electronics differences make it much harder than keeping everything within the same series.

 

ah crap. okay thank you guys

 

IF....you do end up swapping out all the electronics...and would like to sell the s5 engine harness and s5 battery harness...i would be very willing to buy them providing they are in good condition...

 

you can use the s5 electronics but youve got to use some type of standalone

 

iani1.1 is correct and so is rotaryrocket88...i've been through this...actually currently still going through it...if you want everything to work right and this is the route you've chosen to go, do yourself a HUGE favor and go standalone...or you will want to kill yourself...lol. believe me.

 

okay guys thank you very much, theres one thing i want to be certain about, i am buying a s5 turbo engine and want to know if the engine harness will properly attach to my car although is NA
