Like it says I'm doing an OBD0-OBD1 conversion for my 89 crx si with a B18B1 in it. I got the harness and ordered the distributor. Am I going to need both front and rear o2 senors?

Also this harness came with 12 extra wires and I have no clue where they go. If there's anyone out there that has done this your help would be greatly appreciated. Thank you in advance.

 

the harness u bought should come with instructions

 

duuurrrr, still lost.

 

talk to someone you know that has done a few swaps b4

 

im about to do the same swap. my motor came the distributor, 02 sensor, and the injectors obd1. i think all i have to do is get the axles 90-93 integra, 92-95 ecu manuel trans, and buy a jumper harnes.

i assume im still going to have to re-wire the injectors, disty, o2 sensor
and im good?
or is there something else to do?
where is the best thread on wiring all these things?
