which harness is easier to use for swap
87 n/a i am converting it to a s4 t2 engine. which harness is easier to use the s4 t2 harness or the stock n/a harness. i could not find much info on it. i would rather not use my stock harness because it has been cut up by previous owner and i will be getting a harness and computer with the new engine.

A TII harness is a waste of time. A replacement NA harness would be easiest.
The S4 NA and S4 TII EM harnesses both plug into any S4 ECU. There is no wire missing from the NA harness, unless you're talking about a knock sensor hookup.
Using the NA harness only requires extending TPS & BAC wires, and cutting one unused wire.
Using a TII harness requires re-pinning the EM harness to Front harness plug (NAs and TIIs have the pin locations mixed up), and running all new wires for the alternator plug (on NA EM harness, but on TII Engine harness).
Click the link in my sig for more detailed info on the rewiring needed.
