So I got three gauges I put in and none of them work, they are all of the electric type, ya ya ya you should buy mechanical, well whats done is done and I dont feel like running oil and tranny lines into the cab. Any way...one of them is an oil pressure gauge which when connected just pegs all the way over to 80psi and then the stock one stops working, if i unplug it the stock one works again, both are hooked up to a stock pre-86 sender. The other 2 are trans temp and oil temp and I checked all the wires and what not but i still get nothing, I do have the wires run through a quick disconect plug as they are in my new center console. Does anyone have any ideas, cause im stumped? Thanks
