wiring help

[PKRWUD]

I can't believe they would suggest that, that's such a bad plan. If that's the way you want to do it, go for it, but you'll regret it big time. Not only are you running unnecessary amps through your ignition switch, but you are doing so in a much longer circuit than is necessary. Your going to be pulling 15+ amps from the battery, into the car, through the ignition switch, back into the engine compartment, and up to the fan. If you used a relay, the circuit carrying 15+ amps would go from the battery to the relay to the fan. Rather than going through 15 feet of wire and an ignition switch, it would go 3 feet, max. The longer the wire the amperage goes through, the thicker it needs to be. Otherwise, you run the very high risk of melting the insulation, and shorting out your electrical system.

In laymans terms, it would be like living in a duplex, with your front door right next to your neighbor, but instead of stepping a few feet to go from door to door, you build a bridge that crosses the street, and then build another to come back across the street.

It's your call, but if you want to do it your way, forget using the wires we've suggested. You need to run a heavy gauge wire from the fusebox.

Good luck.

Take care,
