There is a really slick mod detailed on website for Toyota Yaris where some guy with a wiring diagram figured-out that all you need to add Cruise Control to the Toyota is install 2 low-power momentary contact switches that you can buy for under $10!
Seeing the write-up here on swapping the Insight Wiper Control Stalk to get Variable Intermittent Wipers made me wonder if a similar upgrade to Cruise Control is possible on the Fit...
Anybody with a wiring diagram got time on their hands to check this out?
