1969 tri power
 

Did the 1969 400HP 4-speed with air conditioning use an idle control solenoid or was this only used on automatics?
Thanks.

With a serial number of 18283, I would guess it would have been built about midway through the year.

All cars with A/C had the solenoid is the heavy gauge pink wire still there tucked away on the firewall somewhere ?

Must be taped-up with the wire harness as I don't see anything out of place. It would have some kind of plastic connector attached (perhaps cut-off) but nothing is visible that I can see.

I found an old thread on this look above

here is the thread, on the bottom of the picture from the AIM it states with M20 and M21

Thanks, that was very helpful and answers my questions!
