just to clarify....(thank you for your patience in advance)...my confusion seems to stem from...on the IVR the top prong wire leads down away from the gas gauge and connects to a terminal near the ampmeter. The middle prong wire is a black wire that leads to the main wiring harness. The bottom prong wire leads to a condensor. So....if I understand you right (I'm embarrassed )....Unplug the top wire from the IVR and leave it unplugged. Then hook up the blue lead from the wiring harness to the gas gauge terminal(blue wire already connected). Can I run both blue wires (harness and the one thats currently on there together)....or should I pull the current blue wire off? Thanks.....
