need some help installing oil psi gauge. its electrical. i have the power and ground connected so that it lights up, but i dont know how to connect it...it came w/a thing called a sender, and it looks like it screws onto something, but i dont know what...basically everything is connected but the signal wire

take out your stock sending unit and put the one for the guage in. Then just mount the guage and run the wiring. Your car will tell you to check your oil all the time but it's better than drilling and tapping another sending unit hole in your block.

you likely need to buy autometer adapter part number 2278.

here this might help
