lol, I know what you mean!!! I haven't put a piece of cardboard infront of the radiator yet, i normaly do in the winter. Now, I don't mean to sound like an idiot (even though I are one, hehe

) but can you explain the wiring for the manual grid heaters because I am DUMB when it comes to electronics.
There is nothing to electrical, don't hook up the red's to the black's and you're fine 
Seriously though, all you need to do is located the grid heaters two terminals, they will have larger guage wires on them. The wires run back to two solenoids on your drivers side fender well. The relay has smaller wires attached to it that are the energizing circuit leads. You just need to place an additional set of wires onto these terminals so you can run them to your switch in the cab. I wouldn't bother messing with factory harness beyond that. Leave the warning light alone. If you want a simple solution, buy an illuminated toggle switch and put it somwhere where it stands out so you don't forget to shut it off. Put it on the accesory circuit so you can't accidentally leave it on when the key is off and drain the battery.
Hope that's explanation enough. Much more, and you'll need to just bring it by and I'll do it. (the commute will be a rough one though)
Hand me a wrench and I'll go to town, tell me to wire something and I'll crawl into a hole. But hey, gotta learn sometime! I just know there are some decent gauged wired that connect to the relay solenoids. I'd be worried about amps burning out my switch, or am I looking at the wrong wired to tap into?? And could my dumby light just be the wait to start light? Is there a way to wire into that as well? sorry for all the questions!! But, Niki, I do try and point the front of my truck away from the wind, cause it does make it worse! Thanks for your help guys!!
