    I've just gotten done doing all this too. I changed all terminal ends in connectors. added dilectric grease
    to all connections. New blower, relay, resistor and switch inside. still no high speed. But thanks to all the great responses
    i will now go double check the red wire to see if it is a good connection at starter. Thanks to all who help us figure things
    out. Now to see if i should trade my 76' 250 6 cyl for a 350 2 bolt short block 86-94.... decisions decisions

    from the starter to the relay from what I remember. its direct battery power, full 12v. If it's at the relay, follow it. if not, find it at the starter. if not, maybe someone can show ya a pic of theirs. my car was a V6, so i think it'd be different.

    I set mine up today, you MUST have vacuum from the engine going to the gray and purple lines. Use a T setup and tie the lines together. You should get air from vents.
