Looks good. How about some closeups of how you mount that overflow/wwwasher fluid tanks?

Could just run a couple thermo switches. One slightly higher temp than the other. So, under normal circumstances, only one kicks on, if the truck gets hotter, both will run. (although, that's a friggin' 60 amp draw isn't it??)

Could also have the a/c compressor circuit wired to a relay to turn on one of the fans when the compressor is running.

Thanks, I will get some close ups. Basically I just took a welding class, so this was kind of a project to test my skills. I welded two arms from the top and bottom of the frame around the electric fans and conduit clamps to secure the tabs of the washer fluid tank to the arms. For the coolant over flow I used a piece of sheet metal formed it with an angle to attach to the frame of the fan shroud, then used a metal nibbler to cut the tabs out the same as the factory plastic shroud.

The idea about the temp switches seem good. How though would I wire the relay switch on to come on with the AC compressor though?

Wire the relay into the compressor circuit. Compressor is powered thru the relay, which is controlled by the PCM. When conditions are 'right', PCM triggers relay, which simply sends power to the A/C clutch, and then it runs off to a ground. So, wire the relay control circuit right into it. wire from compressor clutch to power input terminal for relay control, hook other side to the ground terminal. Fan runs whenever a/c compressor is running.

Thanks for the suggestion. I TRIED the cheap thermo controller and it just looked terrible and I was afraid the probe wire would get damaged causing the fan to not come on. I decided since this is a critical part of taking care of my engine, which is being rebuilt now to tune of $2000 ~ I decided to not skimp and purchase a Derale dual fan controller. I think since the fan shroud turned out so well and I saved over $400 doing it myself, I just decided to get the dual controller, the same controller TCP uses on their fans( which I can't afford ).

I will try to keep an update on the fan build as soon as possible.

Default Installed E fans

These are the e fans installed. The odd circles are train horns i decided to put in with the available space provided by the e fans.
