Great advice, thank you.
I pulled the cluster last night and resoldered (melted and added a small amount of new modern solder) all the connections on the back.
Everything seems to be working great except the WTS (Wait To Start) light still isnít illuminating. The fuel gauge came back to life and started working so now I have two fuel gauges 🤣 the factory one and the aftermarket replacement.
Iím pretty current the glow plugs are working fine since itís 50 degrees F outside and the engine starts instantly. So I have to figure out why the WTS light isnít coming on... maybe the bulb or the housing. I suppose it should be pretty easy to trace out the connections leading to it and double check them too..
