Fuel pump test connector

96 suburban 350 vortec. Fuel pump has intermit problem. In the autozone web site they say to apply a 12 volt jumper wire to the fuel pump test connector. Located on driver side of engine comparment. Has anybody used this connector? What does it look like. I did find a female connector wire coming out of a big wire harness. Not sure if that's the one

what 'i' would do, is just -replace the (fuel pump )- relay/
that is what you are trying to test.
FYI-usualy 'u' can just -move a known-good relay to the questionable slot.

It should be red colored wire that comes out of the underhood fuse block, also remember that there's a redundant power supply for the fuel pump which is your oil pressure switch, so even if the fuel pump relay fails, as long as the engine is cranking, and oil pressure is building up, the switch will close and allow voltage to go to the fuel pump.
