What do i need to wire this dash?

Posted by admin on Nov 12th

I have a 72 Challenger and i have ALL new wiring harnesses,including aftermarket guages..speedo,water temp, oil pressure,fuel and volt.Each guage has a bulb for illumination with a pos and neg wire.Do i need to combine all these wires into one pigtail and should i wire these bulbs into the dimmer switch…and if so which wire(s)in the dimmer switch should these be connected with. i have 6 bulbs and in the dimmer switch i have 2 yellows,1 brown and 2 blacks.1 black goes into the light switch,the other black into a plug connector.1 yellow goes into the map light the other yellow into another plug-in connector.the brown one goes into the fuse box.can i assume that the positive is the brown and the black that goes into the light switch is the neg?
