cruis control wiring?
 

Can anyone help me with the wires that go into the cruis control vacume actuator thing i dont know what the actual name is but im trying to figure out what each wire does and possibly just wire it up to two switches like in a semi if possible. there are four wires: solid black, blue w/red stripe, green w/red stripe, and tan w/red stripe. Im not sure if this is the right direction to go to get the cruis control to work or not heck the vacume actuator thing could be bad for all i know but any help and input is apreciated thanks in advance. :pca1:
