Quick question 88-93 CK w/cruise control

Ok here is an easy one, under the dash, to the left of the steering column is the cruise control wiring. According to my manual, and backed up by seeing it, there is a 'switch' called the cruise disconnect switch, but apparently this is different from the on/off in the stalk.
How it works is,
when the stalk is on, the pink wire has +12v and connects that to the gray wire in the column. This gray wire goes to the servo module under the hood and tells it that its to be on, then in the harness the gray wire splits to another gray wire, this goes to this 'cruise disconnect' and is light green on the output, then this light green runs into the brake pedal switch and is brown on the output and heads to the servo module (stick shift trucks add another switch on the clutch after the brake pedal switch.
I think because the connector to the cruise disc. is why my cruise is not working (I got the truck with the wrong stalk installed, the previous owner had some real retards working for him)
anyways, what I need is for someone to drop the 4 screws on the panel for directly under the steering column, and look 'up' to find the lt green/brown pair on the brake pedal switch, then trace that harness down to where the gray/lt green pair break out and tell me what that plugs into or does it have a 'slug' plugged into it.
thanks

Hey, Quaddriver, I see you're working with 88-93. Closest I can get too is 94. I'll be happy to look at it if you think it will be the same.

in 94 the cruise servo changed and it uses the actual brake light flash to disengage, that middle switch aint in there (I have wiring digrams 88-98 :-)
but ne'er mind thanks anyway, I fixed it, I jumpered that plug, twisted pink+gray, went for a drive and touched dark green and bingo, cruise. held blue on and it accelerated, held dark green and it decelerated. right now Im soldering up a circuit board with some leds and gonna put some momentary switches I have in the dash - beats paying $50 to HELP! for a stalk when I have the parts for free
