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.

Fuel gauge diagram


All of the dash gauges and warning lights get power from the same pink/black wire. You should have a pink or purple wire coming from the sending unit in the tank that provides ground to the gauge.

I have a97 chevy c1500 the fuel gauge never worked,so i put a new sending unit in still dont work gauge reads past full @all times can anyone help


Your problem with you fuel gauge is not the sending unit or the gauge in the cluster. You have a broken ground wire in the the harness that goes to the sending unit. look for broken wires or wires that have bin picked with a test light they will have corrosion

Do you have a wiring diagram for the gas gauge on a 1987 chevy r1o pickup truck


I don't have a diagram but I can tell you the pink wire going into the tank should be the sending unit for the gauge.

1984 Ford F150 Fuel gauge reads empty


I would bet the sending unit is bad but lets check it, a good test i use is that i have a used sending unit i connect to wiring to test the gauge and wiring, if the gauge moves when i move the testing unit then i know the gauge is good and the wiring to, locte the connector at fuel tank, and unplug it, this will be the one the leads to top of the tank and the connector will be on the side be the frame on drivers side, the way you know you have the right connector will be the truck will not run as this connector has the sending unit and pump wires in it, if the gauge goes to full then you know the wiring is good and the gauge is good, you can jump the two wires and gauge should go to full also. the problem is you must get the right wires for sending unit or you may pop fuse, let me see if i can get you a wiring diagram or just do the full test by unplugging connector.

Okay, your sending unit has a yellow and white wire, thats the sending unit wire, the other is a ground and we wont worry about that. so if you want to see if gauge will go to empty or full just unplug connector and gauge will move to full then if you take a wire and jump the yellow wire with white stripe to a good ground the gauge will go to empty, the thing is your gauge is on empty so sending unit may be grounded out, good day10_21_2012_4_15_34_pm.gif

Fuel gauge dont work i put a new fuel pump in it and it still do'nt work 1997 blazer


Was the wire harness replaced from the fuel sending unit to the frame, it's a good practice to replace the wire harness when the sending unit is replaced. The wires are know to break and cause sending unit issues from weak fuel pressure to faulty gas gauges.
The other possibility would be a faulty connection to the stepper motor in the gauge it self or just a faulty stepper motor that would need to be replaced. You can do a search on Ebay for stepper motors for your fuel gauge which runs for around $15.00 which is much better then $400.00 for a new cluster if it is and bad fuel gauge stepper motor.
Thank you for using fixya and good luck.

Need to attach new electric temp. switch/sensor where aftermarket mechanical one is installed


The factory wire to the factory gauge is a solid green wire. that year truck the sending unit usually mounted in the drivers side cylinder head but i have seen some in the passanger side if they have cut the wire and you can goto the main harness connector under the brake master cylinder and booster and find the only solid dark green wire and follow it forward to see how far it back they cut then just splice and run it to your new sending unit . If you want to check to make sure the gauge works after you find the solid green wire put it to a ground and the gauge should go to hot if it does not you have a bad gauge or a cluster wireing in side the truck and that is why they put the aftermarket gauge in .
