SOURCE: Replace oxygen sensor for 4cyl 01" Accord - wires don't match

Don't put a universal oxygen sensor in your vehicle. You will have nothing but problems, and you will have to put an OEM one in it anyway.

Fuel pump wire color

The gray wire goes from the pump relay to the pump. The black white wire is the ground for the pump. The purple is for the gauge on the dash and the black is ground for the sending unit. I don't list a white wire being used.
If the colors on the truck don't match the tank, you'll have to test them to verify each circuit.

Need color code on new connector

Just did my fuel pump on the 2001 isuzu rodeo. Well here is what you need to do about the different wire colors. First disconnect your negative battery. Drop the fuel tank and replace pump. Remember to have a splice kit in hand. Ok now here is how you connect the different colored wires. Black goes with black. Gray goes with black and orange wire. Purple goes wit blue and yellow. And the last wires goes together. I hope this helps.

I have a 98 grand marquis. im looking for the fuel pump reset switch. where is it located and what does it look like? and also im looking for the power wires to the fuel pump that come out through the...

it will be in the trunk you may have to pull pack the liner to see it. it will be to the rear of the wheel wells.

it will be a black piece with a red button. press the button down to reset

there should be a dark green with yellow with and a pink with black wire at the inertia switch. the dark green is power from the relay and the pink is power to the pump. there will be another connector on the passenger side of the fuel tank. the wire color to the pump will change at this connector.

What wire is the power for the fuel pump at the pump

there were some production changes in 1998 to the fuel pump wiring, so the connector can have 2 diff fuel pump power wire colors, the most common color is grey, but the the harness at the tank has just 4 wires, the larger wires at the four wire oval connector are the fuel pump 12 Volt and the other is the ground, it is black, the other 2 wires are the sending unit, also the connectors ( Chevy factory service bulletin) on this year had a problem with burning, so if you get a new fuel pump always replace the 4 wire fuel pump connector. I have attreached a picture of the connector

The wires should be grey, orange and black, purple, and a black wire. The purple goes to purple, grey to gray. The orange and black goes to the small black wire on your car harness and the black goes to the bigger black.
