on a 1998 Mitsubishi Eclipse 2.0 motor on the fuel pump there is a grey and light blue which ones positive and which ones negative?
I'm just wiring up a fuel pump which has a positive red wire and a negative black wire and
I need to connect it to the factory blue and gray wires but I don't know which one is
negative and positive
If you have a multimeter you can just stick a probe on each wire. If you happened to put the postive probe on a negative wire, the voltage read out with have a "-" minus sign in front of the voltage readout. Switch probes do it again to make sure you have a positive readout this time.
