I got a voltmeter guage from summit the other day and i am lost on how to install it--electronics is my downfall--anyway I got the bulb hooked up to my headlight switch and that works but i dont know how to hook to volmeter up--it says hook it up to any accessory but I dont have any accessorys--no radio or cigaretter lighter--so i tapped it into the fan switch and that doesnt work cause it fluctuates when i turn the fan on--so where do i tap it in to? Im super lost

I believe you want to hook it up to the GAUGE POWER wire -- usually RED.

To get the most accurate reading, snake an 18 to 22 gauge wire from the positive terminal of your battery through the firewall to hook up your guage. Make sure to get a fuse holder and wire it in the line as close to the battery as possible top rotect against shorts. (A car battery can deliver enough current to catch a small guage wire on fire if it is shorted!)

i thought a voltmeter was not supposed to be hooked up to the cars battery? I thought i hooked it up to an existing accessory or something--

I would not hook it directly to the battery, because you don't have a manual disconnect as you would wiring it after the switch. I always go by the philosophy that anything and everything will ******* up and build to keep those things from being major problems instead of minor annoyances.

I agree with Woodz. You don't need the gauge to be powered when the car is off. It should be wired after the switch. You can go from any fuse in the block that is powered after the switch is turned on.

[rustyrazer]

so you are saying I should wire it into a fuse in my fuse box that is turned on when my cars ignition is turned on? Give me a example--also how do i wire it into the fuse box? I know where the fuse box is but after that I am lost

[horvath]

There's usually a plugged set of wires on the column that include stuff that gets powered from the key switch being in the on position. If you can figure out where those are going and find a POWER wire, you can plug into that with a flat connector and add power to your gauge ... like I said earlier, one of those will be a wire that powers your gauges.

Try following the wires FROM your gauges to the column to see which wire is powering them and add your new gauge wire to it -- AFTER you disconnect your battery cables.
