I need a hot wire

[jaketime81]

Where is a good place to wire my fan? Looking for hot wire when on, but turns off when I turn the car off.

Might want to reconsider that. If running very hot and the motor was turned off it would boil over for sure.
I think the best thing would be right off the battery. With a safety switch for trail repairs. That is if your "car" ever sees trails

That's no different than if you had a mechanical fan. I think you'd be fine going to switched power. You should have a fuse block under the hood, tap into something in there. If the fan draws alot of current, go to the battery and wire it through a relay tripped by a switched circuit.

that's the way to do it

Not sure what you mean by that, btw, your pic doesnt work

I ran mine into the heater fuse. Yeah, the mech fan turns off with the motor so I dont see a need to run right to the battery either. The electric fan conversion if great. Had mine about 2 months now and no problems. What kind did you go with?

fuse box ...Use your rear wiper if you got a soft top

no one???

Do you mean my hard top?

Its a 91, ford taurus brand. flex a lite was out of my budget.

Hi,

Routing a fan through the fuse box without a relay is a real bad Idea. Most of those fans pull up to 30 amps, so tapping off of most any circuit is going to overload it, as most circuits in the fuse box(es) consist of smaller sized wire (since they mostly power lights).

If you use a relay, You'd get power for the relay's switched side (for the fan) either straight off the battery terminal of from a main distribution box (if equipped) which has large sized (at least 12 gauge) wires supplying power to it. Then you'd hook the relay's coil (trigger) circuit to a switched hot wire from the fuse block. In this setup, the fan is drawing all it's power from the battery connection, and only very little power is being drawn from the fuse block to trigger the relay. :mrgreen:

Note that you MUST protect both the relay's switched hot input wire and the relay's coil wire with fuses or circuit breakers. You'd probably use a 30 amp fuse for the switched hot input wire, and a 4 amp or less for the relay coil wire.

Sorry I didnt mention that I have the whole thing wired, with a relay, fuses and all, im just need to wire the relay trigger into a swiched hot wire.

I think what he was referring to was that some JEEPS might take it personal if you go around calling them CARS. The rumor is that if your JEEP hears you call it a CAR then it will start having all sorts of mechanical problems. It's best not to chance it. :lol:

cigarette lighter

or but a chiltons or haynes book. Those will tell you what leads are hot.

I get it, your broke chevy might overheat, while my jeep crawls all over it.

Then pretty much any soure will be suitable since the trigger (coil) side of the relay uses very little power. If you don't want to splice into a wire, look and see if your fuse box has any extra slots for options you might not have. If it does, and they are switched, use a spade terminal to tap into that spot.

Otherwise they do make a wiring device which is called something like "add a circuit" or such. Basically it plugs into the spot of any fuse in the block, then the fuse plugs into it, while at the same time it provides you with one or two female spade terminal taps from that circuit.
