just recently had my car tuned and found out the boost controller option isnt working with the a/c button. when the a/c button is activated the ecu doesnt acknowledge it is turned on. i have a MAC boost solenoid and i have it plugged into A11 port on the wire harness to the ECU. my ecu is a p72 and i have a 95 gsr turbo'd. i have removed the a/c compressor and i have also cut the 4x2 plug on the passenger side that, from what i believe activates the a/c compressor, so i can use the 4x2 plug to wire in my resistor box for a plug and play setup. the a/c light on the dash does come on with the blower motor, but like i said before the ecu doesnt acknowledge it either. im unsure if im suppose to wire something else up to the ecu from to the a/c button or any other button i would like to use to control high and low boost settings. yes, i did get the boost control option with my ecu. i have a synapse engineering wastegate http://synapseengineering.pinnaclecart. ... -31-1.html.
for me to use high boost i have to run the boost solenoid hose to very bottom port which can read 13.9+ lbs and if i want to use low boost i would then hook the boost solenoid hose to the second port from the bottom up. my low boost is 10lbs and my high is 15lbs. back to my main question, do i have to wire in an additional wire to activate low and high boost? if so, im thinking about using the cruise control button since i may have to use the blower motor to help cool my motor if need be. thanks

Re: boost controller option wiring
You will have to look at the diagram for the AC switch to see how it is wired and rewire it so that it either completes the circuit or breaks it.
