ohc wiring diagrams

I'm looking specifically for engine wiring diagrams or a more complete ECU pinout for the 1.8 sohc non-turbo if anyone might have something. I have the one off autozone's site, but it is a little generic. Thanks!

I don't know if this will help, but most all wiring diagrams can be found here:

Hope you are able to find what you need

That's the one I have now, I'm just looking for something a little more detailed that maybe shows every ecu connection.
Thank you though, I didn't realize that was there.

So that diagram is actually more complete than I originally thought. Only 4 pins are missing.

I have what I need from the one posted, but here are the missing ones if anyone knows their whereabouts or is interested in maybe helping a complete pinout:
C1 is the BLK/BLU connector toward the front of the car, C2 is the RED/WHT connector toward the rear.

C2 pin 3 WHT/BLK ?
C2 pin 7 ORG - all other oranges are "hot at all times," so I suspect this one may be also ?
C2 pin 23 WHT - (or off white, it's old...) looks like it might be a slightly heavier gauge wire
C1 pin 6 LT.BLU/ORG ?
