In search of a good hot lead.....

Ok, went wheelin the other day, got pretty stuck in the mud, and toasted my thermostat relay for my electric cooling fan. What I want to do now, instead of the thermo, I'd like to wire it so it comes on when the ignition is on, ie, the motor is running. Any one know off the top of thier heads a good place under the bonnet to do this? My volt meter is arcaic, and a little direction would save me alot of time. Thanks.

When i put my voltage meter in mine, i found a couple of loose wires under the steering column that had terminals on them, but were not connected to anything. They also were directly connected to the ignition switch, if you hunt around there some where you will find somthing that will work.

How about this:

No matter what you do, you are going to have to install a relay, so the main draw from the fan comes directly from the battery, so, any thing in the engine bay that runs constantly once the ignition is turned on will do as the switching source wire for the relay, but i reccomend you use the wire directly from the steering column as the switching wire, as it is possibly the most reliable source.

Use the ignition switched-on wire for the fuel pump relay. That's what I used for mine.
