90 Crx Wiring Diagram

[Crx Guy]

I was wondering if any one had a good Wiring Diagram for a 90 Crx... I think HF. At any rate I just need it to connect up some wires for the B16 I am putting in it.
Thx for your Help

If your putting in a B16 then the wires are already there. You just need to run 3 extra wires, one for the knock sensor, one for the vtec solenoid, and one for the vtec oil pressure switch. The HF engine harness will fit right onto the b16.

Acutally you have to run 4. knock, vtec sol, vtec oil, and 2nd o2.

This is the diagram I use when wiring on a mpfi car:

you can just tap into the 1st o2 if youe don't wanna run the wire all the way to the front. but that's the ghetto way.

Yes forgot to mention the second O2.

The car will run, but this is not good because you're splitting the voltages.

Or, run BRE or turboedit. The only difference between OBD1 and OBD0 is the 02 sensor. If you're running a wideband, it doesn't really matter.
