Firewall plug pinout for OBD0->OBD1
I'm using a D16Z6 engine harness(I don't have a MPFI harness to begin with, and don't plan on buying one), and I need to convert the shock tower plug on the driver's side(I've already got the passenger side figured out). Does anyone have a pinout for this, etc?
Thanks

helms for both the car, and the engine will have the wiring info.
after you spend 160 on manuals and pull all your hair out trying to figure it out, then you might realize a few key points.
1) theres no where near the correct amount of wires on that facotry side becuase theres a ton of extra stuff on the mpfi and z6
2) if you modify the factory harness for MPFI, then get a conveter from rywire for the obd-1, itll actually work.
3) even if you did wire it up with what you have pictured, theres too few wires on the interior harness that acutally plugs into the ecu. do you have the 3 male plugs for the obd1 ecu? if you dont then you need a conversion harness anyway.
so basically you need all the knowledge of someone who makes conversion harnesses, THEN you need to wire up the 2 shock towers with the wires that are there, and then run all the extra wires through the firewall to the ecu, then cut all 3 pre obd plugs off the and hand wire all the obd1 plugs on. thats like 60 connections.
then pray to god you havnt crossed even one that will fry the ecu. but it should be easy since the wire colors change 3 times before it gets to the ecu... (sarcasm)
overall, not the way to go. im sure its been done.

The ECU plugs(passenger side) are done. I used some wires from a main harness from a 93 Civic EX. I don't need to wire 60 connections; because it's done as I already stated. I just need to wire about 16 connections+injector (+) wires. So close, but so far.
I've searched the helms manual, but it doesn't say much about the main harness/driver side wiring. In the pic, one connector looks to be just Ign. Switched power(yellow with black stripe), so I'll probably just solder all of those together and setup a relay.
As far as the actual canon connector on there, the Z6 one only has 3 extra wires(on the CRX the 3 extra are plugged/blocked off) plus that connector with those 2 thick wires.
