The problem with cooling on mine is all due to the crappy VSC contoller. When my fans actually do kick on the temps drop and stay steady at about 180* (w/a 160* t-stat) even in 80+ degree temps. However, I find that my A/C compressor isnt turning the fans on or the temp switch. So I usually get under the hood and push the wires on the VSC and wiggle it and somehow the thing comes on. I think that when/if I get a tune I will def. wire them to the PCM, its much more reliable.

Allen at Nelson Perf is designing a wiring harness for the flex-a-lites to run by the PCM. I think Brian at PCM-for-less is doing the same.

But electricity is another story - whenever people start talking about stuff melting and then just upping the fuse rating or wire gauge, I start backing away slowly, and stay away from/out of whatever it is they've been working on. 
I would love to replace my mechanical fan with electric ones, but I've heard too many stories here and other places about batteries dying mysteriously or stuff blowing up to consider it at this time. It seems the fan manufacturers are doing a one-size-fits-all for their products, with mixed results. If people were corresponding with the fan manufacturers and working out issues properly I would have more confidence, but at this point in time, there are no concrete answers, just guys scratching their heads and rigging something up that sounds good to them. So I am backing away slowly....

The only thing I would change about the PCM controled e-fans is to have one come on when the a/c is turned on. Maybe you could do one at low speed then have the PCM kick them both on high speed? Isn't this the way the Camaro's do it?

Is this suppose to run in conjunction with his Tune. If so when will it be out. I am getting tired of this damn VSC controller, it works half the time and the other half of the time it doesnt. And my temps fluctuate too much between 180-205, I need a computer Tune w/ E-Fan option to make it work like a charm

I'm not sure is running them at half speed is going to be adeuate to keep the truck cool in warm climates. I tried this first (which is why I had my wires crossed up in the first place) and wasn't very pleased with the results. To get 1/2 speed, you need to wire the fans up in a series, then have them in parallel to get full speed. It would be possible with a creative array of relays to have them turned on low with the PCM, and have then hit high when the A/C is on. Problem is going to be getting the fans to turn on HIGH when it gets over operating temps WITHOUT the A/C on. The trucks PCM has only one fan control while the cars have two (one for low and one for high). To the trucks PCM fan control, 200* temps is the same as 250* temps.

ok ok. i have run the wires the correct way. i used the wiring they sent. i have followed the instructions to a tee. i wired up three sets at the same time. yesterday before the diff broke they fried. and didnt even blow the fuse either. the vsc looks like berut. i will get some pics tonight.
