Re: fan question
Mark, if memory serves me right you can tap into the green/white striped wire at the fan relay and connect it to a toggle. That should ground the relay and turn on the fan manually. Since you are not connecting to a power wire, no more fuse problems and no resistors needed.

Re: fan question
for $30 at Pep Boys you can get a wiring harness for up to two fans, relay, and adjustable dial from 80* and up! I say, save yourself the head aches.

Re: fan question
That's what I did with mine - I wired in a seperate fan controller because I always had issues with the factory fan switches going bad, and I got tired of getting a face full of coolant everytime I had to replace the switch. But I used a more expensive Flex-a-Lite controller that has provisions for switches and such. It was easy to install, has a probe for the radiator to get temp, fully adjustable, and has worked great for 3 years now.
