I was messing with the Tech2 in a parking lot and came across an entry labled "Valet Switch". Anyone know what that's about? Not mentioned in my owner's manual or a cursory search in the main shop manual.

Underneath looks good for being in Yankee territory!

did the swap to the dual 700w cooling system 7/9 blade, it's pretty apparent that it is heavier duty than the stock dual 5 blade, fans and motors are bigger and have more weight to them. installed brand new motors in the housing so I should be golden for a good while.

You have info on where you got all your parts? I may be interested in this. Seems like a nice mod especially for those in hot places who do a lot of towing.
