Cruise control wiring

I have a 90 GM column, 05 5.3 with drive by wire and the cruise control is not working. I need to make sure I hooked the wires up correctly and I have searched for a wiring diagram for the cruise, only FOUR wires, and I have not found one. I tried Painless, Autozone and just Googling looking for it.

I found it on here this site.

Thanks.

Re: Cruise control wiring

Ok, I still have issues.

The PSI controller has the following:
Grey is the on/off
Dk Blue cruise set
Black resume

The GM switch on the column has the following colors:
Blue
Red
Yellow
Green

I think the Red would be the switched power in, the blue might be cruise set, the yellow the on/off and the green the resume, but it's not working.

So back to the multimeter.
