Can one of you guys that have done these give me a few pointers? How did you get that plastic light plenum on the top out? Looks like it is held inside by compression on the center metal piece below the silver button on the face. I do not want to mess it up. Thanks

Or if you can find a non center console gauge, it has the oil temp element already

I finally got that plastic out. Scored it a thousand times with an exacto blade. I actually want an oil pressure gauge in there. I will find and old small VDO and use the guts, I have an extra fuel gauge module. That should give me a good start. I’ll need to get someone to make me a face plate, I may need to send it to an expert to have it calibrated and a plate made. Thanks for the ideas.

I just read that the fuel gauge and an oil gauge basically work the same. But the ohms are different. Has anyone here already learned this and found the correct circuit to make it work correctly. Fuel gauge is up to 75 ohms and the oil gauge is 180 ohms. Thanks
