G54b 2.6 carb A/C idle up help.

I just recently installed an A/C setup that I got from a junkyard "87 ram50 4x4 2.6 G54B I installed it in my "88 mitsu MM 4x4 with G54B I retrofitted it to R134a. Added a new receiver drier, and it all works in some capacity, but the problem is I'm not sure how to add or adjust the a/c idle up on the oem Mikuni carb, I have the OEM solenoid and wiring here, but I need to know how is the stock vacuum ines setup for the a/c idle up system, the A/C works when your on the freeway or when you're driving, but in city driving
I have to turn on and off the a/c at every stop sign to keep the truck running and this is for obvious reasons dangerous, so how do I add the idle up on my truck thanks for any help.

The harness for A/C should have a plug to hook up the a/c idle up solenoid. Otherwise, tap off the a/c clutch wire and use a relay to apply 12v to the solenoid when the clutch engages.
