I bypassed the clutch switch on my Mccruise. Not sure if yours is the same though. The two drawbacks are it will start in gear and clutchin it to kill the cruise is a little delayed. It will cause it to rev up a couple of hundred rpm before it drops to idle. I gonna live with that. No biggie to me. Have you emailed or called Rostra? They may solve your problem. When I called Mccruise. The guy ran me thru some tests. It passed all the tests. He said it wasn't cruise related. I bought 2 new clutch switches. That wasn't the problem. Best luck on gettin it going. Once I tasted the cruise. It would be ruff going without it.
