Ok, im planning on swapping in my built d16z6 pretty soon into my 1989 Hatchback DX, but im still trying to figure out the wiring problem i have. Im staying obd0 so that means im using SI intake manifold, and SI dizzy, and the PM6 ECU. I have an UNCUT CRX SI engine harness that i wanna use. How can i make this engine harness fit on my car? The plugs on the firewall of my car are to big to fit into the plugs on the CRX SI engine harness. What do i do? I dont want to buy a DX harness and convert it, because i have no more $$. How can i make this CRX SI engine harness work? Thanks!

You need just the harness in the engine bay right? (dx). if i dont sell mine this week when this kid comes to look, ill give it to ya for $40, my car is 89 civic hatch dx.

 

dont wanna buy another harness, i want to make this SI harness i have work, how can I?

 

You shouldn't be using the Si harness anyway. Just use your existing DX harness, and add the necessary wiring for MPFI and VTEC. Just use the search function on this site, the info is there. Search under DPFI-MPFI or something to that effect.

 

It sounds like you don't have the original harness.

So, sell the SI harness, and buy a DX one to modify.

simple as that.
