My friend and I are putting a b16 in his dx. I have done the swap in my Si already. Now, I have a spare Si engine wiring harness kicking around. Can we just sub that in for the DX harness and get the Si - SiR Hasport harness ($75 instead of like $200)

Lemme run that by you again.
DX harness - garbage
Si harness - replacing DX harness
HASport harness (Si to SiR) - added on to the Si harness.

Would this work? Once again, this would be nice because we would have 0 downtime as well as much cheaper seeing as how we have that extra Si harness.

 

still won't start. the dx is a 12 plug and the si is an 8 wire plug if i remember correctly. you'll have to rewire the injectors and a few others.
