Re: Suburban A/C fix + Vintage Air?

Two things I need sorted out that I'll take opinions on.

1. Need to trigger the electric fan(s) when the compressor kicks on.
(This is a carbed LS motor with MSD box - how the fan gets triggered)
How should I do that?
Edit: The answer is a Trinary Switch

2. The Rear blower needs a switch and power run to it. Thoughts?
I have heard that with rear units, you want to run the fan anytime the AC is on to prevent icing. Can I trigger it from the front fan unit? Via a relay maybe?
that way when I put the fan on, and the AC is on, the rear unit also gets power?

Just making my to-do list, and the above are still in the "idea" phase.

It's going to be hot today, but the show must go on!
