I have a 91 vert n/a with the hopes of doing a tII conversion on it. The problem I have is that the tII parts are s4 motor,omp,manifolds, turbo and j spec harness. I will be buying the haltech soon e11v2 can I use the s5 n/a harness with the s4 parts along with haltech and not go through getting a front cover waterpump and intake manifolds? I want to do this until I can get all the s5 parts after the s4 blows will I need anything else from a S5 turbo to complete. thanks and I did search

 

seems you and I are in the same waters, needing to have a JDM right hand drive car harness meet our na usa cars. Its a lot of wires.
