It does not look like aftermarket. But it could be. and if it is. it is probley going to come off. I dont use Cruise. And i could get rid of that dang wire. So just let me know what yea guys think. Also that box is not even attatched very well. And i do hear a hard vacume when i take off. And i am getting kind of a Low idle when i am sitting. Think that might be what it is? creating a vacume leak?

 

It's aftermarket cruise control.
That's a design I haven't seen before, with the servo and module all in one. It looks very old.

 

ok, well do you think there would be any harm in taking it out? Ill disconnect the vacume line this weekend see if that stops the idle issue. Ill have to track down where the rest of the wires run to. This is going to be a pain. WTF would someone put something like that on a truck for. that did not have it.

 

i added something similar to my '96 ram.it was an extra large vacumn cannister with check valve that a freind gave me.it solved all my vacumn trouble.if cruise,and heater controls all work properly i would leave it there.

 

i just have to try the cruise out. I dont get to drive it during the week usually. So ill give it a shot this weekend. i am just happy i figured out what was going on.
