Again I come to the mountain for help. Any of you gurus have any idea what this is and why it's here? The chain on the inboard side goes to the throttle linkage just forward of the firewall at the upper joint. The vacuum lines come from the manifold (tee'd off another line) and goes to a switch on the brake pedal. I think that's an interlock switch to keep the engine from starting without the clutch being depressed. I can't find it in any of the manuals I have......

Aftermarket cruise control.

YAY!!! Thanks! I was thinking maybe part of an autostart system. they're real common here, but I couldn't find any of the other bits that would go with an autostart. I can probably pull that ugly thing without any issues i imagine.
