purpose of obd2-1 harness?? No luck on the search
From what i know, you only use it if your engine is obd2 and u use it with an obd1 ecu. Or am i completely wrong on this? Would you still use it if you are using an obd1 ECU and an obd1 engine? the car its going on happens to be a 2000 civic.. thanks for the info

If you are putting an OBDI motor into a 2000 Civic and using the OBDI ECU then yes you will need an adapter harness. The first OBDII is acutally for 96-98 Civic's, and the plug styles changed in the 99-00 Civic. You would need the 99-00 OBDII to OBDI adapter. You'll have to use the 00 stock engine harness on the OBDI motor which means rewiring the distributor, injectors and a few sensors if you keep all of OBDI electronics on the motor. The best thing to do would be to use an OBDII distributor and injectors.

you also use it if you have an OBD2 ecu and want hondata, which you have to have OBD1.. (unless hondata has OBD2 stuff now)
most chipping places won't chip OBD2 ecus.

What makes the OBD1 distributor and injectors different than the OBD2?
Is the distributor connection plug wired differently? If so.. then why the injectors?

This worked the other way around when i put an obd2 engine w/harness into my obd1 car.
Just a thought

Why can't he use the obd1 engine harness and plug it into the obd2 chassis harness? This way the obd1 dist and injectors would work.

I'm confused. By one piece do you mean that the harness that goes on the engine, goes straight into the car with no plugs to connect them?

#2-Connectors for OBD1 and OBD2 injectors are different. OBD1 use square connector with metal retaining clip. OBD2 use roundish/rectangular connector with plastic release tabs.

With mine, a 94 Civic Ex, that I swaped a b16 into, I swaped my injectors, harness, distributer internals, and ran a Mugen DOHC Chip in my P28 ECU.....I think this is a way to do it, I HOPE!!!!!
