Hey guys. I am reinstalling my poor mans stroker and I have these wires/connectors on the cabin side/ecu side of the b25 engine harness. What are they for??? 
also. Do any of you have a 4pin o2 sensor good or bad you would let go of? I mainly just need the connector end with enough wire to spice a mustang o2 in. Thanks.
