GS300T68

i have a 1999 lexus gs300 with a supra tt swap with a t68 single turbo and an aem, when they did the swap i guess they never kept the plug for the ac compressor so it is not wired up, does anyone have experience on what i have to do to get that wired up?? which plug i need what wires go where etc..... all the wires are there next to it but they arent hooked up to the ac compressor
second question:
what are the wires on our GS300 that we wire the turbo timer to...also will the supra plug and play work or not.......

thanks again
