i am swapping a b20z2 into my 1991 si crx. the b20 has been switched over to an obd1 motor with harness and i am using the crx interior harness with it so i baught an obd0 to obd1 jumper harness for the ecu which is a p28 chipped with LS mod ive got all wires pluged in on the motor side and all on the inside i am wondering what i would have to do or splice and witch wires i would have to cut to get them to connect any help would be great. really need the car done thanks.

 

so youre using the obd1 motor harness with the obd0 interior harness?

 

your not making a whole lot of sense. which wires dont match up? assuming it was done right, your now obd1 harness should plug right into your shock tower plugs and then your ecu jumpe will have its own wires running to the harness. should look something like this:

this is a DPFI to OBD1 Vtec conversion harness i made, but you get the idea

 

Ok i understand what it should look like i just need a diagram of what wires do what and whick colors they are at the towers to cut and splice
