AutoMeter wiring help
I bought a 67-72 gauge cluster that has had AutoMeter gauges added to it. It has oil pressure, water temp, volts, and tach. Unfortunately a previous owner has simply clipped all the wires and senders. The oil pressure gauge has a small copper tube attached so I think all I have to do is run the oil tube to it. The water temp has a stiff black cable so I'll probably have to find a replacement sender. Not sure where to get it. The volt meter probably just needs + and ground wires attached. The tachometer has 3 wires; black, red, and green. Any help with the correct wiring of the tachometer and suggestions for the other gauges will be greatly appreciated.

Re: AutoMeter wiring help
Your Oil Pressure and Water Temp gauges are mechanical. You can run a new 1/8'' copper line to an oil pressure port on the block, but I think the water temperature is a whole unit -- the gauge, line and in-head temp probe are sealed in an all-is-one unit. I could be wrong. Contact Auto Meter customer service/tech line to confirm.

Re: AutoMeter wiring help
I have a 3-3/8'' Auto Meter tach, p/n2650-504. Mine has no wires coming out [except black + white instrument lighting leads]. It has three male spade terminals: one terminal marked ''Signal'', one terminal marked ''+12V'', and one terminal marked ''Ground''.
We might guess the red is for 12VDC, but both green and black are used for ground in different applications. One for ground and one for Tach pickup. Ground lead goes to a chassis ground. Tach 'Signal' lead goes to coil Negative terminal [points] or TACH terninal on HEI. So to avoid frying your tach with the wrong guess, it's one more question for the A.M. tech rep. Email them at: service@autometer.com or call: 815/ 895-8141

Re: AutoMeter wiring help
I think I found the info on the tach. Red to +12v, Black to ground, green to the coil. I'm going to buy a new water temp meter. I think that should get it all going.
