Hope this can help anyone that wants to use an aftermarket fuel gauge. May already be a write up on this but I couldn't find it. I decided to go with aftermarket after not being able to find a cluster with one that actually works correctly. Used one from Glowshift. Regardless of what gauge brand you use, results will be similar. After a few trials and error I got the new one working with no cel and gas lights on. I chose to mount the new gauge where the ashtray is. Didn't take pics of how I wired power to it but I just used wire taps on the constant and switched ignition to the stereo.


Under the back seat I chose to just cut the green signal wire going to the fuel pump sending unit. With this wire not connected you will get a cel for high signal input. It uses a variable ground signal from the sending unit. You will also get the low gas warning light and dte will flash. I used a 47ohm resistor and grounded the side going to the body harness and hooked the new gauge up to the side going to the pump. Ignore the butt connectors. This wasn't the finished product. It was soldered after everything was working right.


If you ground the wire without the resistor, you will still get a cel. After it's all done with, my oem gauge sits right above half and I have no cel. You should be able to use any resistor between about 10 and 75 ohms. I opted for 47ohm since it was in the middle of the resistance values of the sender. Last pic of where it sits with it all finished up. I'm happy with it.

Awesome! But now where do you put your cigarette butts?

I don't smoke so it wasn't used.

You know... there's a thread on how to fix the cluster. Costs $0

I searched everywhere and never seen anything on it. Posted in several places trying to get it figured out with no answers. Only thing i found was a business in NC that the cluster could be sent to and repaired for $150. With this virus crap going on, everything i order gets delayed by several days to a week. Its my dd so that's not an option at the moment. Over half the links on this forum don't work or sends you to something totally different than what you clicked so

Here you are if you want to fix it. It's probably equal in difficulty to what you did. Getting the needles to align up again is tedious.

Thanks. Im gonna ride with what I got for now. Its definitely a cluster issue though. Today the needle dropped to almost a quarter tank. Sometimes it will go back up to just above half and thats with the resistor on the wire to ground. All else fails, ill rely on the trusty trip meter lol.
