my reverse sensor is un plugged and when i put it in reverse the check engine light come on there do the sensor wires go in the ecu plugs?

 

oh-oh, very interesting.
Is your car a DX? If so, what year? Did you specify the year when you were ordering from hasport?

 

same thing happened with my swap, i just took a pin out of one of the slots, i forget which one, it was so long ago. But once i took it out i dind't throw any codes, engine ran great, and reverse still works and the reverse lights still work, if u were wondering

 

try to remember the pin and the color of the wire.

for the other ? it is a 89 hf

 

Unplug driver side shock tower wiring harness and make sure that wires match up when plugged. Simply move the wire to another slot so they touch when plugged. Make sense? I had the same problem when i orderd my wiring harness from Hasport.
