I'm doing a complete swap from an 89' crx dx to a b16a1. Instead of using the dx wiring harness, i bought a 90' crx si harness and I am going to convert that instead. I was wondering if anybody can give me a website where i can get some good quality step by step instructions of doing this wiring.

 

Wiring will be a lot simpler with an Si harness.

What you will need to do is add VTEC wiring, knock sensor as well as convert the intermediate harness to Multipoint.

You can do the multi point by following this site:

As for wiring up VTEC:

Follow from VTEC solenoid to the A8 Pinout at the ECU
For VTEC oil pressure sensor, this goes from the oil pressure sensor to the B5, and you may tap the ground to the oil pressure sensor at A4

As for knock sensor - this goes from the knock sensor (which is mounted at the back of the block near the cylinder head) to B19 pinout at the ECU.

the Si engine harness is not compatible with the DX cabin harness - better use the DX, unless you want to change cabin harness also
