I just replace the dash in my 1995 C2500 Suburban. Everything works except now I can shift from park with out depressing the brake pedal. I notice there is 1 connector with 2 wires in it by the brake pedal, but I'll be darn if I can find where they go. Wondering if this is my problem.
Thanks

The interlock circuit should be some thing like this.

From the fuse block fuse 16 a 20amp fuse for turn signals and brake lights a pink wire should go to port C of the Park/Neutral Possition Switch connector on the left side of the transmission. Out of port B of this connector should come a light green wire which goes to port C in the Stop Lamp Switch on top of the brake pedal. Out of port D on this connector a dark green wire goes to port A of the Brake Transmission Shift Interlock Solinoid on the right side of the steering column. Fron port B of the Brake Transmission Interlock Solenoid a black goes to ground G200, behind left side of instrument panel below the fuse box.

Hope this helps
