This condition of poor set point control is a plague of all vehicles I have owned.
Why we get no control is baffling.
Accustat AS-90, any .25 of so fuse holder.
Or a Honeywell th1010d2000 also good only for 1 amp. This not my choice as I will reserve it for my heater & is for you to test. In battery mode it should work, being a relay stat & not a SS relay, but it may not for 12v even though I see no reason it should not. I like the simple operation of the former. You may have to play w/ the installer setup to get a similar cycle rate.
Find the blue/green stripe 18 ga or so wire coming out of the plug somewhat behind the AC on / off button.
This wire energizes the compr clutch.
It is ~ a 2.1amp or so duty. The stat is good for 1.2 amps max.
So you need a helper relay NO contacts to make the blue wire and let the stat make the relay coil. Which can go in the area behind the switch as well. I took power from the cigarette lighter with common blue squeeze take off jacks.
There you go, perfect AC control for your tin.
