what it this? From 86 suburban
This was behind the gauge cluster and attached to the speedo. Is this part of the cruise control?

Yep, Drac box I think it's called. Lockout converter if your truck is an auto too.

Re: what it this? From 86 suburban
Its not just for cruise. It is the optical sensor that gives the ECM the speed info from the speedometer since the truck has a mechanical speedometer.
It attaches to the back of the speedometer with a tiny self tapping screw.
