87 model year. Where is the "amplifier" for the cruise control. I know it's under the dash, but it would be nice if I knew what it looked like. The cruise worked on the Bronco before I did the swap, which included changing the cruise servo over from the donor truck (cruise control functionality unknown), so I'm going to guess the servo is the problem, and I need to follow the troubleshooting diag, but need to find that silly box.
