Talking there is no switch on the gauge so i needed it to turn on and off with the dash light

there was black, orange and white for wires on the gauge and the black went to ground. the orange was supposed to be positive and the white was to go to the dash lights to turn on the gauge. I didn't want to mess with hooking up three wires so i just hooked up the black to a current ground on the steering column mount, and twisted the orange and white together and hooked them to the dash light wire. was easy except for getting the dash apart. Theres a LOT of steel back in there!!
