voltmeter?????????'s

[94opalgt]

ok its going in by the instrument cluster and i dont know which wire to hook it up to.the instructions say to hook it to a switched wire to get the volts reading,so which one do i use?i know which wire to use for the lights in the gauges but i cant figure this one out.any help?

what exactly are you hooking up?

You can use any key-on hot wire for an aftermarket voltmeter. Here's a tip: Take your DMM (your handheld meter), and let the motor get hot. Put a full load on the charging system and measure the voltage of the wire you want to use. Compare this reading to the reading at the battery with the same load condition. If there is a large voltage drop at the wire you want to use, you know your new in-car voltmeter will read a little low. I would find a wire/circuit that doesnt have the voltage drop.

Good luck.

Couldent you just splice into the wires for the stock voltmeter?

As long as there is not an IVR on 5N95's, you could. I dont know if there is one so I might not do it, unless one knows for sure.

all i really need is a color of wire to look for.like the wire for the cluster lights is light blue with a red stripe.if i cant figure it out i'll just pay someone to put them in for me.
