I need to know what all u need to change to obd 1 in my 89 civic hb. I already have a dist, ecu jumper and a ecu, is there anything else that i need

 

get in touch with locash racing. they deal with the OBD conversion kits. i believe they have complete conversion wiring harnesses for a few hundred bucks.

it saves a lot of headache and time if you arent electrically inclined.

 

i already hav the harness, i just need to know what all i need for the conversion. Read the original post!

ok, well you call it an ecu jumper.

anyway - i meant the ENTIRE wiring harness. the thing that goes to all the components, not just the harness conversion. sorry

 

4 wire o2S!!!

 

does anyone know where I can find a diagram for the dist wiring?

 

you will need to match the colors from your obd engine harness to the new obd1 distributor wires. you will need to get a distributor connector/plug from an obd1 engine harness so that you can connect one plug to another, or visa versa and switch the obd1 distributor connector to a pre obd connector so that you can mate the two together. you can keep the stock injectors but will need to keep your resistor box, or the other option will be to get obd1 injectors. also you will need a 4 wire o2 sensor.
