the air con is a seperate loom, but it's also plugged into the main loom for various points of reference

the air con loom is not a stand alone loom though as it's wired into the main loom

you will need the wires for the heater controls mainly and then follw them back, keep everyting you need that is connected to the air con from the car and dispose of the rest

it's not the end of the world but it is a pain in the arse, the ecu needs to get 2 sets of feed from the ac loom though, the one where it turns it off when you are cranking and under wide open throttle and also a feed from it to raise the idle when it's on
the idle thing you can probably get away with by tricking the ecu into thinking the heated screen is on, the others though might be easier if you just forgot about them and turned it off when you were booting it or ran it through the engine running relay

i did the same thing on mine before i realised i need to lose the ac to get the turbos in there
