So, is there a harness I can buy to do this? I mean, do I have to splice and connect wires if i want to do this swap? just wondering if there was an easy way to take care of it. thanks.

 

You can send the dx harness to me, then all you would have to do is switch a few wires at the ecu.
PM me if interested.

Take his offer. This conversion along with B16a wiring took me a weekend to figure out what exactly to do, then another weekend to actually do it. And I actually spent this Saturday re-doing a lot of it as my original work wasn't up to par.

 

if you have basic wiring skills ( soldering , splicing , depinning) and a good guide (search h-t) , it's not hard. it would probably take me a bit because i like stuff to be perfect. if ur time is worth a lot , it might be worth it in the long run to pay someone to do it if it's cheap enough.

 

I took the main harness and the engine harness out of a wrecked Si and swapped everything over! had to do a little splicing between the main harness and the body harness as the donor was an 88' REX SI and it went into a 90' DX
