Thanks for the reply about the purple wire... I appreciate that.

Now, for the questions I had/have...

Is there a wire from the PCM that is supposed to control a relay to power the coils? If so, which one? Or, do they just get powered when the key gets turned on? If thats the case, all I need to know is which wire(s) on the coil packs need(s) power? I can feed them without problem using a relay to control that. I definitely see the injection and ignition controls from the PCM... assuming that those just go from the PCM to the individual coils and injectors to control their timing. Anyway... like I said, where do I need to feed injectors and coils? Please? Thanks!

Coach!

hey here are the wires you need
99 LS1 PCM to Front Harness

Large Plug C100 Plug
A PNK Hot in Run and Start (IGN/INJ Bank 1 15A)
B DK GRN/WHT PCM 43 A/C Clutch Relay Control
C DK GRN PCM 18 A/C Clutch Status
D GRY TPS +5v to TCS
E DK BLU TPS signal to TCS
G PNK Hot with IGN 1 Relay Engaged (Tranny/EGR 15A)
H DK BLU PCM 33 Cooling Fan 2 and 3 Relay Control
J DK GRN PCM 42 Cooling Fan 1 Relay Control
K BLK TPS sensor low to TCS

C101 Plug
A YEL/BLK Low Coolant Sensor
B PNK Hot in Run and Start (IGN/INJ Bank 2 15A)
C BRN PCM 36 Air Pump Relay Control
D DK GRN/WHT PCM 9 Fuel Pump Relay Control
E PNK/BLK PCM 19 Ignition Positive Voltage for PCM
G ORN PCM 57 Battery Positive Voltage for PCM
H BLK/WHT Ground
K GRY/BLK PCM 53 TCS Spark Retard Signal to Brake Control Module

C105 Plug
B PNK Hot with IGN 1 Relay Engaged (TCC Stop Lamp Switch/MAF/O2 20A)
D DK GRN PCM 37 Cruise Control Inhibit
F WHT PCM 13 Cruise Engaged Signal
G WHT PCM 10 Tach out to Brake Control Module
H PPL PCM 4 AIR Solenoid Relay Control

These are all of the pins/wires I did not use:
220- E,H,J,K
230- A,C,F,G,H,J
C100- B,C,D,E,K
C101- A,C,K
C105- D,F,H
All the pink wires run into one wire which is ignition switch on i ran it to my ecm ignition on fuse on my truck fuse box. and the orange wire i ran a hot wire to it from my battery. the ground wire i hooked into my ground turned the key on and bang she started. dont know if this helps or not but might. good luck

these are the plugs on the end of the engine harness the three plugs. use them this will power everything up for you and it will power up the coils so you dont have to power each up. hope this helps

I wanna say THANKS for you taking the time to post that info. It backs up some of my educated guesses and fills in a lot of blanks for me. I can now get some wiring done! Kick butt! Thanks again!
