I just installed my Air fuel guage in my 93 hatch. I ran the ground wire and the power wire to my radio fuse and everything lit up fine. I was told to attach the last wire to the thick white wire on the center plug of my ECU. When I turned it on, it wouldnt light up!!!!! I have a P28 ecu and an LS/Vtec and its a VX. Please Help FAST!!!! My car is just sitting there. Any ideas anyone???
