Manula idle
I bought the cable from AW Direct as shown in one of the above posts. I than mounted the knob in the cigarette ligter hole. (dont smoke and still have power port) It is a perfect fit. I than ran the cable to the Injection pump. I cut it to the right length mounted it though on of the holes im the Throttle bracket. Than I use the chain supplied in the kit to hook to throttle lever. Put some RTV or silicone where ti cable mount to engine or you will get significant engine noise in cab.
Works great. On a cold morining I give it three full turns ( will vary depending on install) and she idles at a constant 1000. The reason I installed it was for cold starts. When Cold the pedal is hard to press and I would get a high rev, not good for cold engine. Than I would quickly let off and it would stall. With the new cable - nice controlled starts.
I have also used it as cruise control on very low traffic night driving. It isnt the safest, but once you are comfortable with it all you have ot do is push th knob in and it returns to idle. Since engine does not compensate for hills truck will slow and speed up. But consistent fuel flow gives unbelievable mileage!!
