Hey guys I just joined so I am new to the group, but I need some help with my late 80's K5 Blazer!
Previous owner powered the fuel pump with romex fed from a 20A ignition space in the fuse block
. I am trying to use the factory brown/white wire. I have traced it from the tank up through the bulkhead connector. It does not go through the fuse block though, it goes from the bulkhead connector to a plug behind the instrument cluster that is not plugged into anything
. This doesn't seem right to me? Where does it need to plug into to get 12V? The pink signal wire takes the same route, but plugs into the back of the instrument panel into the printed circuit board as it should. The fuel pump relay is new. PLEASE HELP!
