1990 Silverado Multi Function switch
How do I know which multifunction switch I need. Not sure if my truck has cruise control or not. This is my first Chevy. The switch was gone when I bought it. There are 4 wires : yellow , blue , red and green

Look under the hood - if you have cruise control, there will be 2 cables attached to the throttle body. One leads to the gas pedal and one leads to the cruise control module, which should be mounted on the driver side firewall.

I see you have the old style interior (1988 - 1996, if I am not mistaken). I have a '98 and the cruise is a 3 position switch on the stalk and a button on the end. I would assume if yours had the same setup, if you had cruise, their would be a hole on the end of the stalk where a button used to go. I could be completely wrong, I do not even know it those years had cruise control, I assume they would but that is about it...
