OK im installing my autometer and i need to know exactly which wire the light and power wire should run to. My friend said we should wire the power and light wires into the cruise control wires but im not sure where to run the tach light wire to, any help GREATLY appriciated thanks

 

You need a 12volt power that turns on with ignition, parking light wire and a solid chassis ground. Oh, and a tach signal (usually blue at the distributor or blue single wire plug near passenger side underhood)

 

were is the parking light wire ?

 

should be in the harness in your steering column. what car?

 

You need one to a power source. One to a ground on the chasis. Another wire to instrument cluster, if you want to do it the easy way, find your instrument cluster fuse in the fusebox and you can stick it in with the fuse, or else find the wire that runs to the fuse and splice it (that's what I did). Then the last one goes to your distrubuter. And, if I remember correctly, the color of the wire is the green one with and white stripe. I'll check mine in a few to make sure.

 

That mashing wires into fuse boxes is not good. Causes arching, possible fires. What car? Ill tell you all the colors.

 

95 ex coupe, need to know a wire to splice into for the tach light wire for power

 

Ignition is black/yellow stripe at column
lights are red/black stripe at fuse box
tach is blue at distributor
ground is obvious

There ya go, boss.

 

thanks a lot, i appriciate
