Toggle Switches

[Ryguytoodry]

I want to run toggle switches for the interior light, exterior lights, and an electric fan. Has anyone done this? How did you go about wiring it up? The car has no turn signals, running one headlight, both tails.

I have a new dash wiring harness, so the only toggle switch I need (electric fan) I go directly to the battery,when I do my new sound system everything will be in the trunk with 12volt conector blocks fused. I will never cut into a wiring harness again lol. Good luck. Dennis

put switches to ground side for the lights.if the fan pulls above 18 amps run it through a relay setup.battery power to fan and ground activated through relay by the switch.much safer then running high current through the switch.

X2 on what 67 said. I just wanted to point out why he says ground side of lights, most interior lights have 12V all the time and rely on turning the ground on and off (door switches ground when opened). All you have to do is ground one side of the switch and run the other to the - side of the light.

I'm trying to run as little wiring as possible. On one switch I want to run my exterior lights (one headlight, and tails, nothing else), 2nd switch is interior light, just the dome light. How could I go about wiring these up? I'm stuck with loose spaghetti under my dash right now because I don't know which ones to remove...

Unplug your headlight connector and test to find which terminal has 12V, use that for your headlight toggle switch feed and then take the wire from the dimmer switch that goes out to the lights and hook it up to the other terminal of the toggle. You will have a few unused wires. For the interior light there should be a ground wire in your headlight switch connector that turns the dome light on, to find it "once you have determined none are live after removing the headlight feed" just start grounding them until the dome light lights up and hook it up to one terminal of the toggle with the other terminal grounded. Make sure whatever you use for the for the headlight toggle is rated for the amps, if not use a relay. Keep in mind this is without knowing what your working on, a wiring schematic is the only way I can be sure but this will work on most.
