Today I was able to mark another thing off my list. I was successful in getting the computer to know when the A/C was on. I literally spliced in an 8 inch long piece of wire so pin #10 on the computer received a 12v signal to alert it to compensate for the A/C. Now when I turn the A/C on or off, the idle stays the same.
While the car was on the lift, I also planned out my next task which is the emergency brake. The stock system used a horizontal lever that multiplied the force that the driver pulled on the in-cabin handle with. I plan to replace this with a vertical lever mounted left of the transmission. My exhaust system forced me to abandon the stock setup. I'll attach a new lever to the bracket that holds my clutch slave cylinder which should allow me to pull the brake cables with enough force to engage them.
