Hey I found everything for cruise control off a 92 cherokee at a junkyard. Gonna put it in mine but I was looking through all the wiring and came across an issue.

There is a black wire that runs from the cruise control module to the servo. I found it in a manual and it says that it is a ground wire. On the servo end of the wire, it has a black connector but I did not see anywhere to connect it to the servo. Did I miss something or is it not needed?
