I do not have the 160 t-stat. I have thought about it and may do it soon. No on the MAF, but I have a call in to Tim.
I do have the twin 15" Flex-A-Lite fans. Picked them up from a friend that owned a speed shop. I was going to do the install myself but had to send the truck back to them awhile back, so they took care of it. I had them install an aux. temp control switch in the cabin. That fan really messes up other H2 owners because it keeps running after the truck is turned off.
Notice the splice in the top radiator hose. That is for the fan's temp control switch.
