I finally got tired of the oil pressure gauge reading low due to the stock sender going bad. I also didn't like the stock volt meter gauge either so I replaced both of them but I installed them in the stock/factory gauge cluster! Here we go:
I used a piece of sheet metal I had hanging around and cut it to the same size as the stock face and had to guess the best I could to get the gauges center
First test fit
I didn't take pictures of the back side but I did have to open it up to allow the back of the new gauges to fit properly. Final for, painted the new face black
Before I started the swap, I changed the bulbs to green LED lights, here's they are lit up in their final position
I also drilled a couple of holes to add some red LED lights for the low oil pressure warning. I have two at the gauge and one on my main cluster
And I lied, I did take a picture of the back showing what I had to cut out and also the wiring
You can see here that I wired everything up to a wire connector so if I have to take this out of the dash I can just unplug it.
Wiring was pretty easy, just 4 wires:
Ignition wire (factory Dark Blue) went to the + of 12v gauge AND to the positive of red lights for low oil pressure. The negative wires for the low oil pressure lights went to the pressure sensor (factory grey wire). Dash lights + went to the factory orange wire and negative side of 12v gauge and negative of dash lights went to factory black.
I hope to have it all together tomorrow- will post pictures of it installed!
I am working on a 1994, I'm sure 95 is the same but I don't think 96 and up would be the same. I would imagine later models would be pretty similar. I had to use 2 1/16 gauges due to space.
