Hi guys
I'm doing some wiring on a is300 ms3x and we do not have the factory ecu. I'm wiring flying lead from scratch. I would like to get some ideas on how to wire up the ac compressor. What inputs and outputs are you guys using? Do i need to wire to the pressure switch as well?
Thanks in advance guys

Re: AC wiring help Lexus is300
I have used Nitrous1 as the idle-up output to my AC relay coil-ve and Tableswitch as the idle-up input which is connected to my pressure switch. That way if the pressure is too high/low the compressor will not run.

Re: AC wiring help Lexus is300
So referring to the diagram above i can wire the Nitrous1 to the Blue wire (pin2), and Tableswitch input to the (Y/L) wire on the pressure switch? Or do i need a 12v source for the pressure switch like a relay?MegaMicra wrote:I have used Nitrous1 as the idle-up output to my AC relay coil-ve and Tableswitch as the idle-up input which is connected to my pressure switch.

Re: AC wiring help Lexus is300
My AC is a very simple system compared to yours. Before I connected anything up to the MS3X I tested it first by grounding the AC wires I was going to tap into to make sure it worked correctly. I'm sorry I can't help any further.
