I didn't know what forum to put this in, since it's electrical, I thought I would try here.

I have four guages i want to install in my car, A/F, water temp, oil pressure , and fuel pressure, all electric. Where do i get the accessory power wire from? I had three of these guages installed in my other car and when I shared the acc wire with the radio and all the gauges my A/F guage didn't work any more. So any ideas?

Thanks

Home Depot.

 

haha

I didn't mean where to buy the power wire. I meant where do i get the wire in the car. Should i run a fused wire from the battery to a relay for each guage or is there an easier way?

All these gauges can be powered from the ACC wires found in the main harness from the ignition switch. Run a fused line from the heavy gauge wire that shows 12V when you put the key in the ACC position and you're done. For the lights, do the same at the dash light comming from the parking light circuit.
