Alright, having FUN wiring up my 96 LT1 with LS1 Conversion, needing to see if I could get something similar to the following link on shoebox's site but for the LS1, he has everything listed for the LS1. The pic shows some of the connectors in question. Not sure if the numbers are the same for the connectors on LS1 as LT1 ex. c100 etc. If someone could please provide this I would really appreciate it and would make my wiring life a bit more easy. 98 LS1 connectors (c100, c105, c210, c220, c230) Thanks

I don't have a scanner, but I took these pics from my manual:

c100


c105


c210


c220


c230


btw, I bought a set of factory manuals for < 40 bucks on ebay, would probably be invaluable to you on this project.

anyone know if this is correct info for a 98 or what year this is?

OEM LS1 Harness ID & Connectors...

The LS1 harness basically connects to the rest of the car thru a few specific connectors. The first four are located in the area of right shock tower...
...C100...black 10 pin connector.
............A- pink (bank 1 ign/inj switched 12v 15amp power in)
............G- pink (transmission/EVAP switched 12v 15amp power in)
............J- dk green (cooling fan 1 relay control out)
...C101...grey 10 pin connector.
............B- pink (bank 2 ign/inj switched 12v 15amp power in)
............D- dk green w/ white stripe (fuel pump relay control out)
............E- pink w/ black stripe (switched 12v 15amp power for PCM in)
............G- orange (constant power for PCM 12v 50amp power in)
............H- black w/ white stripe (ground in)
...C102...
............A- purple (starter solenoid "start" power in)
...C105...black 8 pin connector.
............B- pink (trans/stop lamp/heated o2/MAF 12v 20amp power in)
............G- white (tach signal out)

The other two are located behind the firewall, inside the passenger compartment, on the other side of the firewall grommet.
...C220...natural color 10 pin connector.
............E- black w/ white stripe (ground in)
............G- brown (to back-up lite switch 12v"+" power input)
............H- lt green (from back-up lite switch out to lites)
............K- dk green w/ white stripe (VSS signal 4000ppm speedo output from LS1 PCM)
...C230...blue 10 pin connector.
............B- brown w/ white stripe (MIL lamp)
............E- dark blue (VATS fuel enable input)
............K- dk green (serial data class 2 output from LS1 PCM to OBD-II connector)

The only other two points that the LS1 harness needs connected are down by the LS1's starter...
...purple wire... needs to be connected to the starter solenoid's "S" terminal.
...open ground lug... needs to be connected to a block ground.

The GM color code for wiring is very consistant. When in doubt, the following applies to any loose ends you might end up with in connectors C100, C101, C105, C220, and C230...
...red wires...all loose red wires should be connected to "12v+" protected by a fusible link.
...orange wires...all loose orange wires should be connected to "12v+" protected by a fuse of at least 10a.
...pink wires...all these wires in the LS1 harness should connect to a 12v "switched +" power source hot in "start" and "run".
...black...all these wires in the LS1 harness should connect to chassis ground.
...black w/ white stripe...all these wires in the LS1 harness should connect to engine ground.
