I am looking to connect a performance chip to the IAT (intake air temperature) sensor and ground wires. Does anyone know the color codes for these wires (located on the air breather pipe. There are 6 wires in the plug I believe. The Torrent is a 2008 with a 3.4 V6.

Thanks in advance,

    Try saving it to your computer and you should be able to enlarge it a bit (and hopefully it'll still remain legible).
  • Hi Steve....

    Thanks for trying, but I can't make out the writing well enough to connect the unit. I think the IAT sensor is at the bottom of the diagram and is a tan colored wire but I also need the ground wire in the plug which I can not make out.

    I'll email you a copy of it that may be a bit more legible. You may be able to find some wiring info at a parts store too.
