Fuel pump wiring issues
Ok so I keep blowing my main relay. Luckily I have 5 from the junkyard, but like every week my car will just shut off and then the main relay wont click and the fuel pump wont come on.
I believe its due to my wiring, it was fine before I swaped my whole harness for a 1988 crx si. I have a 1989 crx dx and the wire on my fuel pump have 4 wires and the 88 si harness only has 3. I think its a yellow, black, black grey with 2 strips. and then my fuel pump has an extra black/grey. I know its a weird problem any suggestions would be appreciated.

Look up the electrical schematics for both the 89 dx fuel pump and see what they do and where it goes then look up the 88 si one and see what they do and where they go. one may be an extra gound your not using just guessing without looking at them start there
