Never done the conversion before. i got a 90 Integra LS w/ a 97 B20b turbo motor and am converting over to obd1. Got the distributor,4 wire o2 sensor, conversion harness and a p75 obd1 ecu. Was wondering if anyone got step by step instructions on how to do it or know a website that would. Any help I can get would be really appreciated. Pics would help also if anyone has it.Thanks.

 

If you got the conversion harness, you need only convert the sensor plugs and injectors. The plugs is cut and crimp (or solder). The injectors is a little more detailed as you remove the resistor box and get a junction box where four wires will go from to the injectors, and yes you can keep the old injectors if you wish and bypass that step. There is a wire diagram in the motor swap forum with a full detail of the O2 and other things.

They have everything either included with their kit or can make it all plug and play.
