Jake Brake Buffer Switch

[Tikvah]

The switch in the photo is only for the jake Brake but does not have high idle control.  I have to replace the switch anyway because it's bad.

What is the switch called? 
What is the switch with the high idle and jake buffer in one called?
Where can I find one?
Anyone have one laying around?

The one shown is a obsolete #144351 the new part # is 01-022351,the combo fast idle and buffer switches are close to 800 bucks new fwiw the micro switches are around $400 ea you should get the electronic type replacement for what you have for $200

FWIW Mohawk had the fast idle buffer switch for under 200 a few weeks ago, don't remember the part number i used to find it though. I'm sure it's some kind of aftermarket setup that's been superceded at least a half dozen times.

The parts manual for my MC8 shows the complete fast idle buffer switch assembly (air cylinder and switch complete) as part number 8F-32-12. Mohawk shows that part number as cylinder assembly for  $83.15. I wonder if they have the decimal in the wrong place. If they really have the right part for that price I just might buy a dozen or so lol.

83 bucks is not a bad price on just the fast idle cylinder DD is over $300.00 and the aftermarket junk is around $200.00

Yeah you figured it right clifford. I searched the GM number that it crossed to and it is just the fast idle cylinder. So is the MCI number 8F-32-12 incorrect for the fast idle buffer switch? My book shows that number in 3 places.
