Gavin,
First of all great write up!! I have been contemplating this swap for over a year and actually just recently changed over the whole under dash unit, heater core, condenser, etc. aka the 'right way'... Anyway, i didn't get as much of the harness as I should've so I was wondering if you have any closeups of what wires on the fan switch go to the 4 pin connecter, etc. I haven't even looked at it yet(just too happy to get the auto crap out, and I had the 'good' auto system), but I assume that if there is a same color wire, itll prolly go to the same wire on the other end.
Have you attempted the A/C wiring yet? Pics of that would also be much appreciated, otherwise, I forsee another trip to the part yard for even more donor parts(I actually have all the extra bits to accomplish what you did to modify your old system...just looked at it one day and said f that and got the whole shebang. I def. know how much extra work you did the route you went. Anyway, any and all info is greatly appreciated!
