chevytech..... here is what i found out today.
unplugged the connector at the cruise control box under the hood..

pink is hot when ignition is on... good.
dark blue is hot when pressing the set/decelerate button....good
black with white stripe is ground.....good

i could not get the gray wire to light up when turning on the cruise switch
not sure how to check the brown with white stripe wire, speed signal input.
and when pressing on the brake pedal i am not getting hot on the brown wire.

so i have 3 of the 7 working.
its hard for me to understand what could be wrong when all functions are good coming right out of the cruise switch/blinker arm, and its not reaching the cruise box under the hood ? well, actually i am not getting the terminal to light up when pressing the brake pedal, and nothing when pressing the resume/accelerate button.
what could be interfering with it somewhere from the switch to the box under the hood ?
i double checked all fuses and every one is good....
i think i have hit a wall, at least with my experience...

got any one last tests i could try ?

thanks again man..
