I know once I have time to sit down and really study these plans, I figure it will be easier to put together than it looks. I still have to get over to my buddy's house and look at what he has, his might be simpler.
This one has an awful lot of Electronics to it, from what I have seen so far it has a window detector with a trigger, but the schematic shows it going to a connector which means I need to look at the other part of the print. I guess I should really print it out, probably be easier to read.
I will check with my friend ASAP, he is supposed to be building a test kit out of his plans and wants to use the Ranger as a test for 30 days. If it is done (I doubt it, he works like 12 - 14 hr days) I will post here as well. I believe, if anything, it will increase about 5mpg, that is me though.
