@gnob was right the gauge was faulty. Got my new one in the mail popped it in and everything works as it should. Hope this thread helps someone else in the future. Thanks everyone!

Yup that's what I was expecting... I know the wire exists on the back of the cluster so if not wire is there at the fuel sender I'll run a wire and splice into the yellow and blue wire going to C10.. Thanks!

LOL it does he sent me pics of it. Do you have any experience making this light work on a non SR5 truck? Looks like to me the C10 connection yellow and blue wire is what is uses.

Polishing those contacts was one of the first things I did and it did not help anything. As for my fuel sending unit I am not sure, but since it was a base model truck I am assuming it will be the two wire sender. I am hoping to convert it to a three wire to get the fuel warning light to work...

https://www.ebay.com/str/mmccul3797 Is the guy I bought my gauge from. He was very helpful. Maybe he would have the oil pressure gauge you need?

The Plot thickens LOL I think I figured out what was wrong with mine. The previous owner must have removed the gauge and flipped it around and put it in backwards. I noticed this from looking at some pics of other gauges online and noticed that the fuel gauge looked like it was mounted on the...

I think maybe you are correct and I have a bad gauge. I found this in the FSM: My reading across the IG-E terminals only shows 40 ohms. The other two readings were 96 and 130 so a bit out of tolerance. I am going to source a new gauge and try swapping it out.

I also checked the three resistors on the fuel gauge\voltage meter circuit board and they were all within tolerance. I went ahead and re-flowed solder on all the solder connections and that did not help any.

Yes The top screw you circled is gnd with the ignition off and 12v when ignition is on. The Screw labeled - is gnd all time.

Yup I double checked I never get voltage on pin 5. Checked with a meter and test light. Crap sounds like the gauge is bad. Wonder where I can source one of those? I have one from my 93 Land Cruiser and it looks pretty much the same. I doubt it is though. Could not find any part numbers on it..

Thanks for the reply and bear with me as I try to understand this LOL.. I did some more testing and Pin 2 and 11 on connector C show ground with ignition off then 12v with ignition on. The red screw on the fuel gauge in my pic is constant cround all the time. The top screw you circled is gnd...

I have a feeling that's what's going on. If I apply 10v to the red + and black - in this pic the gauge moved up. If I reverse them the needle moves down. So seems like the gauge works If I trace those wires back I get gnd on the positive and 12v on the neg. So I switched the Red\Yellow pin C2...

Hello Everyone, I am hoping some of you might be able to help me out with an SR5 cluster swap I have done in my 87 pickup (22R) Everything that I have read says this is an easy swap as long as you change out the oil sending unit everything should just work. I have done all that and for the life...

Hello everyone... I am hoping I could get some help with the fuel gauge on my 87 pickup. I recently swapped out the gauge cluster for the SR5 version. My old cluster fuel gauge worked then when it hit the half way mark, it would go to empty. Pretty good sign of a faulty sending unit. Anyhow...

Fyi just got notification of this. Not much help for me since I own an 80. Might be helpful to someone with a 100 series out there https://www.row52.com//Vehicle/Index/JTEHT05J522022719
