Wiring tests for Cruise control (mechanical 1984) 200

Jessie,

Just curious, have you checked the vacuum switch at the brake pedal? I know most Volvo electronics are the first suspect, but this is Dana, and the most common trouble with the '84 cruise is the vacuum leaking at the pedal. Take the hose off of the throttle actuator (vacuum motor) and test it there by making sure it holds a vacuum. Most folks find picking the brake pedal up with their toe gets the cruise working again. If this isn't it, I can find the ground for you tonight. Power comes from an inline fuse at the red/green wire at the brake lamp switch (not shown on the WDM) but derived from fuse 6 on the '84.

Hope it saves you a speeding ticket!
