well im putting new gauges in my dash and am going to replace the speed/gas gauges with something else. my question is, the wiring harness that hooks into the back of the gauge panel...is it for the gauge lights only? it seems to be the case but wanted to be sure before i delete the circuit board on the back. without the gauge panel in the car all of my lights on the outside work and signals still function. i know ill lose my signal markers on the dash, but i can live with that if i have to.
