U velly clever grasshoppa..... I just might bust out the recip saw and do some trimming!!!! Is that a sable fan you are using??? The one I have really kicks butt, but I bet it pulls some amps.... I see the bosch relays and wonder how you wired yours up?? Do you have another thread about your fan install??? If so please post a link as I will get busy tomorrow morning.

I also like your mounting solution for the fan, very nice.
