this has probably been covered before but i couldnt find any info. i tried the search function but it wouldnt let me search for "cx". i have a 92 civic cx with a d16z6 swap. i am using a 95 civic ex engine harness. the ecu is throwing a code 1. i bought a new bosch o2 sensor but no luck. i was under the assumption that it would run fine with the ex harness. are there some wires that i have to repin or do i have to add wires straight to the ecu? thanks for any help.

 

what ecu are you running. you will need to run the wires for the 4 wire o2 because the cx only had a 1 wire

 

ooops...i forgot to mention that i am running the p28.
