Message	So one step I never completed was installing a thermo control amplifier in my vehicle. When I replaced the my EVAP box I switched to a 93+ Evap box that has a thermo control amplifier built in it. From reading the diagrams it seems To me it seems that I need to connect two pins, one to pin 31 on the auto a/c control amp and one to ground.. From the control amp pin 35 goes into the ECU to pin 46 which then leaves the ECU on pin 9 to the AC system.. It is not clear which pin goes to ground on TCA does anyone know, from I can see there is only 3 used pin on the TCA 1toControlamp 1tomanualcontrolamp and 1toGND I see no diagram showing this? Would control amp even properly support? I am trying to avoid having to buy and wire in Nissan Frontier one listed below so I can use all stock z32 components. https://www.courtesyparts.com/27675x-amplifier-thermo-frontier-d22u-1998-2004-p-64469.html?products_id=64469 src="http://pages.prodigy.net/carlosrg/sig05.jpg" BORDER=0>
