Roast!

is the white tach output or input? and where does it go.

Best suggestion is to call or email John. No one knows better than him and he is great at helping.

Orange/black - Park - neutral signal to PCM
yellow - speed sensor signal for electric speedometer
purple - for TCC engagement (there should also be a pink wire with it)
green - primary cooling fan relay control

id call john to make sure but these are all off the sheet i just got with my LS1/4l60e harness from him

Thanks lt4malibu, that sounds about right, but where do I connect orange and black wire on the park/n switch? There are five wires at the
Switch. Would any of these wires keep the motor from starting?

you dont necessarily need it, its to bump up the idle when the car is in gear. none of them should keep it from starting. id check simple stuff like powers and grounds first. make sure the switched 12v source has 12v or better WHILE cranking. alot of the accessories drop out when cranking. also has the PCM had the VATS/theft deterrent deleted?

not sure about the VATS, it has some sort of three wire diode connected, im getting spark while cranking, how do i test if the injectors are working.
