    I have been out of town.
    I have the a/c working, but nothing is hooked into the pcm as of yet.
    After finding out some more information and finding a good deal on a 145 amp alternator ($55 off a new van that will become a conversion)
    I have decided to upgrade the alternator, wiring from the alt to batter, and clean up the wiring for my fans.
    I will be doing all this at the same time I hook the a/c signal wire to the pcm.
    I may not get it done this weekend as I am waiting on a 125amp fuse to come in the mail (alternator charge wire fuse), and I have got to get on the lake some time this weekend.
    I will certianly post the progress notes when we find out.

    Wish me luck.
