Turning an s4 na harness to s4 turbo 2
 

I picked up an 86 s4 gxl from a friend. It came with a t2 diff and trans already. I recently aquired an s4 t2 motor, extra trans and harness, but like most of the s4 t2s that I have seen the harnees is complete shit. I do however have the s4 na harness that was in the car, so I was wondering how t o go about making the na harness work for my turbo application. The first thing I did was troll around the archives found a couple useful things but nothing really explaining everything. Thanks in advance for any help.

.....5 seconds lol no need for the extra harness you just extend a couple plugs and gtg

ya,but he is S4 not s5.
But in a sense it still applies.You need to extend the BAC wires,and a few others..not a big deal.

and cut the PS wire at the ECU..as it would normally go to the knock sensor(after the swap with the N/A harness on there) and the engine would go to lower RPM when you turn!
A search would show you what to do,as it has been done countless times.

Cut off VDI plug & attach ECU wire to knock sensor (Pin 2M)
Plug 6PI plug into turbo duty solenoid (Pin 3R) if you still have it in your car which i do not so this step can be skipped if all the emissions and "unecessary things" are removed
