i have a 99 civic dx. its obd2b and the b16 motor im putting in is obd1. i ripped out my engine harness, and got an obd1 wire harness from a 95 civic ex. i got a big problem though. i still have one ecu plug that goes to the fuse box under the hood. the ecu plug that used to go into my obd2b ecu doesnt fit in the p28. how will i make this plug fit into my p28 ecu?
any help is greatly appreciated. thanks in advance.

NO
You need to use your 99 Civic DX wiring... Put it back please
You can keep your OBD2 injectors, use those on your B16, yes they fit, they're exactly the same.
Next, this is what you need to do:
- 3-wire converted to 2-wire EACV modification
- ECU Jumper from OBD2b to OBD1 - http://www.jkobd.com/2bto1.htm
- Knock sensor (if P30 ECU)
- VTEC
- VTEC Oil pressure
- Distributor Jumper from OBD2b to OBD1 http://www.rywire.com/dizadapters.shtml

We can provide you with a subharness for all your sensors for $45.
