Hey guys i am new to the forum and i had a quick question...
i bought a 99 Civic Si Ecu to Obd2b harness conversion to a 93 civic Si OBD1 and
my question was since they are all the same color on the harness adapter i need to wire up an o2 senor but i don't know what wire to cut into since there all the same color
i was just wondering if any of u guys on here know a place where i can find a wire diagram or anything of that sort

thankz
