    I am searching out those who had fixed their early 90's cruise control . Its the ONLY thing that does not work on my tow rig . All wires are connected , thats all I know so far .

    Learn me , all I have ever done before is remove them , not make them work :thumb:

    I do see 4 wires on the cruise/wipers stalk , they are external and go into the column.

    I have blue , yellow , green , and brown . I am thinking I need a diagram for this system and cut these off and touch the right ones to see if the switch is bad .

    Off a searching I go , please anyone post up advice :thumb:

    it's been awhile, but I think those are still vacuum, make sure the diaphram holds vacuum, and make sure the line going to it is good. and let me know if you need anything else, I can print out a wiring diagram at work if you need one.

    No vacuum , there is a box with the computer and a stepper motor . Cable actually comes out of ther box and snakes it way to the throttle body .

    I wish it was vacuum style . Then I wouldn't want to fix it , I would remove it :thumb:

    It does . Thank You :bow:

    Happen to know which colors are what ? If not I can look for 12 volts and figure the rest .

    And for some reason , I have no fuse marked cruise , no spot for it either . :thinking: Is it on the firewall breakout box where all the spade terminlas for accessories are ?

    The switch itself is usually the first thing to go on these trucks.
