I got this idea from Turbotransam.com in the sticky section, and I'm not trying to take credit for it, but I bought these plugs, and can make the bypass plug if you guys are interested? With this plug when your primary fan turns on the 2nd fan will turn on with it also. I've noticed my temp stays about 20° cooler on average with the 2nd fan running. Plugs are $20/shipped. They're not too hard to make on your own if you choose either. You can get the plugs, and crimpers from Casper's Electronics. Here's the link if you want to see how they're made. http://www.turbotransam.com/forum/index.php?threads/cooling-mod-a-c-pressure-switch-bypass.4336/
