1997 Isuzu Hombre Repair Question
New wire harness for fuel pump, two black wires, does it matter which black wire is attached to truck black wires?
If you get it mixed up the pump will run.in.reverse and wont work correctly.
How do you know what black from harness to hook up to what black on truck?
That's gm wiring the terminal A is gray that's the power feed to the pump then terminal C is black which is the ground to the fuel pump.
I see the letter designation for the different color wires on the old connector harness but there is no letter designation on the new harness connector to know which is the black ground wire?
Use the old one and match it up with new to tell which letter is which.That's all you have to do use it as color key as well that's what I would do.
The new connector on the left is a different shape than the old connector so I don't know how to match them up Because they don't line up the same.
Did the new connector come with instructions like how to wire it?
No it did not
Are the wires to the pump color coated?
Also what brand pump is it?
