    Oil gauge pegs out after LS3 swap

    I have a 94 c1500 and have swaped out the 350 with an LS3 form an 01 chevy. Everything works great except the oil pressure gauge. Its a 3 wire gauge and its not connected to the fuel pump anymore. When I start the truck it just pegs out any suggestions would be appreciated!
