Ok below is the LT1 wiring from the dummies post, and I have marked in RED the few connections I "think" I need, let me know if I forgot any? also I have deleted the following VATS/AC/AIR/EGR/CAT/CAHRCOAL Canister.

| | Top White 10 pin
|K|J|H|G|F|
|A|B|C|D|E|

K is DK GRN and is the coolant temperature feed to instrument cluster.
J is DK GRN/WHT and is fuel pump replay control
H is empty.
G is DK GRN/WHT and is vehicle speed signal.
F is GRY and is fuel pump motor feed.
A is RED and is Alternator feed to instrument cluster.
B is TAN and is oil pressure feed to instrument cluster.
C is BRN and is oil level feed to instrument cluster.
D is empty.
E is empty or if you have a manuel tranny it is the clutch anticipate signal and is GRY.

| | Top Blue 10 pin
|K|J|H|G|F|
|A|B|C|D|E|

K is TAN/BLK and is (Automatic) torque converter clutch control.
J is ORN/BLK and is (Automatic) park/neutral feed from transmission position switch.
NOTE: If this vehicle is manuel the wire would be LT GRN and would be (manuel) backup lamp feed.
H is LT BLU/BLK and is (Automatic) TCC switched power feed.
NOTE: If this vehicle is manuel the would be be BRN and be (manuel) power from turn B/U fuse # 2 to backup switch and would be brown.

F is DK GRN/WHT and is A/C request signal
E is DK BLU and is theft deterrent - fuel enable feed.

|A|B|C|D|
A is PPL and is ignition (crank starter) (connected to starter relay)
B is BLK/WHT Ground
C is ORN Power feed from ECM BAT fuse #4

D is Empty


I believe these are hooked up because I have these connected via an underhood fuse block, which has power and is already wired up to the rest of the harness. But I could be wrong!!

C100. It's connected to the underhood fuse block.
|A|B|C|D|E|
|K|J|H|G|F|

VATS was deleted from PCM.

Trans is a T-5

AC Delete pulley and removed from PCM

PCM is also calibrated to 6 speed.
