wiring blower motor switch with ac

[NDubs68]

hey all,
im having a a problem deciding how i should wire up my blower switch. im rewiring the car with a painless kit and my blower switch is different than the connector and schematics that i have for the camaro. my switch is a three flat with a terminal off to the side and the connector in the painless kit and the wiring books are a "T" shape. the color of the wires going to the switch in the original harness were a gray, orange, light blue, and yellow. in the painless kit has a brown, orange, light blue, and yellow. so i guess what my question is should i just scrap the "T" connector and use the old connector and replace the gray wire with the brown.
thanx
Nick
