Default SPEARTECH wiring question

I have pulled my harness out of the car and I didnt mark the wires.

What are the Thick pink
White w/black strip
Orange
Yellow

I think Pink is the power for the PCM
White/Blk is the tach signal

Finally when I wire the starter to the switch is it just a one wire to it and that is it? I did it before but I forget how I had it.

Mike

Pink goes to your ignition switch (12 volts with key on and during crank)
Orange goes to the Battery (12 volts at all times)
White is the tach signal out
Yellow is the speedometer signal out

For the starter it's just one wire from your ignition switch to the small solenoid terminal (12 volts during crank)

...and of course your positive battery cable to the large post on the solenoid.

The switched 12V to the starter is prewired in your harness right. It is the hole terminal that is wrapped in aluminum heat shielding?

Yes, but it is up to you to get ahold of the other end of that wire (purple) and hook it to your ignition switch.
