ive been looking to see if there is any threads about taking a n/a wiring harness and make it in to a turbo one i herd it could be done and was wondering if anyone knows the steps or how its done

 

Is this for a swap? If so you don't have to do anything to it. The n/a harness will work fine.

 

Rotaryrocket 88 has a link in his signature about doing a N/A to TII swap.
you need to extend a couple wires on the N/A harness to get the Connectors to hook up to certain Sensors.like the TPS.
Look at the Power steering wire too.Ther is one that needs to be cut at the ECU,or what will happen is when you turn the car will Bog a bit.
Hailers had that info in one of his threads.,
I asked about it,about 2-3 years ago,so If you search my name.Hailers name,and Power steering wiring,you may hit the thread.

 

Covered in the FAQ, the archive and my sig. Small changes need to be made for S4 and S5s.

 

It's so easy, its makes u wanna slap ur grandma....

 

wat if your not running power steering im guessing it dosnt matter if i cut it or not even though i planned on cutting it all the power steering and a/c wires any way

 

I don't recommend cutting any wires. Jus tuck them away. If ur not using power steering u won't have a problem. I also run a n/a harness on a s4 t2 swap. U will need to extend tps. And bac if ur running it.

 

what about s5? i have an s5 with TII build on an n/a motor. running all turbo parts with an n/a harness and the car runs like ****.

 

S5 is a little more safisticated setup. Maybe the dual tps setup. Or oil metering.

 

Lack of experience, not the harness fault lol

 

i do have plenty of experience with the rx7 scene, just haven't done a turbo build on a 91' n/a s5 with an automatic transmission wire harness on a car that is a 5 speed with an 86' n/a motor. there is alot to account for, i just need to get the kinks out. the only thing that i have not replaced yet is the wire harness. after i replace it, then everything will be turbo II. if this does not fix my problem, at least it will narrow down my options.
