High-Idle Mod Using The Cruise Control (Great For Winching Applications) For XJ's & ZJ'S all years!

Simple mod, that takes a cruise control servo (preferably from a parts Jeep) and allows you to raise and hold the idle rpms of the Jeep at a steady RPM while you are winching...

This was my first test of the idea, and was only possible after studying the systems wiring diagram from the Service Mauals, and carefully testing how things work in a working cruise control system via a led test light and probing into the oem wiring while driving...

Once I understood how the system worked, I was able to get a cruise control servo & wire harness pig-tail from a 1996 ZJ 4.0 parts Jeep to test my idea and figure out the wiring setup to make it function...

My final goal is to use the rear window wiper switch as the controls in the long run...

Cut its 4-pin connector off the back of the switch, and wire it to a ground source so the switches & button presses will all be grounded outputs to do what I need them to do...

It also has a key-on 12v power source there at that switch too...

I need 3 wires...

12v + with the Key-on...
Ground with the wiper switch in the WIPE position...
Ground momentary output when the rear washer button is momentarily touched. .

That's it!...

Then simply slide the switch to the ON position, and tap the WASH button to set the RPMs where you want them... Then slide the switch to the OFF position to go back to a normal idle again...
