EBL with vintage air?

Have the EBL flash freshly installed, it's a thing of beauty. After fixing a wireing mishap (i had the mat and map signals backwards lol) she's learning and smoothing out nicely. On the stock flash no less.

i did notice there is a a/c request lead, and my idle falls when it's running... Naturally. Wondering what signal? The vintage air has its own brain but I would assume the EBL is just looking for a +12v signal that the compressor is on? So run a lead from a/c request to the positive lead on the a/c clutch and bingo? Seems strait forward but I'd rather ask than burn up my new toy lol.

That's it, run the A/C compressor clutch +12 volts to ECM pin B8. There is an IAC bump along with a bump in idle RPM when active. This also runs the cooling fan.

Do I need to do anything with pin A2? The a/c relay pin?

Only if you want ECM control of the compressor clutch.
