timer harness
 

I have an apexi auto timer the small one that reads a/f ratio. can't find an apexi harness even when I went to apexi
many shops said a greddy harness will work exactly the same without any loss of functions. Is this true? I want to make sure the guy is serious and not trying just to make a sell

Yep, ANY turbo timer harness will work with ANY turbo timer. Dunno who sat down and made a standard for turbo timer harnesses, but the world is a better place :).

From what I've seen, all the harnesses are pretty much the same as far as design and build quality. Just get whichever one's cheapest or easiest to get.
