    As crazy as it sounds, I'm trying to add Stabilitrak to my 04, and it might be economical on time to sling a CompG engine loom in... but I just need to know whether there are any fundamental differences (like wiring for the blower) that'll make a headache into a migrane? Small potatoes like MAP sensor or injectors I can deal with; they're not hard to change! But trying to pin in the individual wires is looking like a bear trap; I'll pin in wires on the dash loom instead! Just a few questions on that: the pink wire for the yaw sensor from the dash plug-in goes to A11 on the underhood fuse block connector (second connector from bottom): is that a switched power source from ignition? Does the pink wire from the steering angle sensor plug into the same source? And can both pink wires be spliced into the harness without ripping the dash completely apart?

    P.S.: I would eventually like to put a mild turbo kit; nothing fancy, just enough to give the car extra scoot! Would the L32's MAP sensor be able to read turbo (rather than blower) boost?

    boost is boost. doesn't matter if it's from a turbo or supercharger. the L32 map sensor will work just fine with a turbo.
