i am going to swap a d16y7 outta a '97 cx hatchy into my '89 crx si. this will just go into place just like the d16a6 right. im really just changing out the block. i know there are a few sensors that will not work right, butas far as the wiring and stuff goes........ can i use my stock wiring harness or do i need a conversion?? i dont think i need a conversion but........ please help me out here because i am thinking about doing the swap in the next few weeks.

 

You will need to keep the A6 harness, using the A6 intake manifold and distributor. Everything else should go right up..

You will be leaving some sensors on the Y7, however such as the CKF (crank flucturation) which comes factory on US OBDII motors and not needed on your stock ECU.

Everything should go smooth.
