I got her all together and love it. Works great and was ridiclously easy. the part number discussed earlier was indeed the correct one, so whoever said it was wrong musta had a clown at the parts dept. Anywho it works great and I cant believe they dont do something like that from factory especially considering the pins are already there. Thanks for the thread WhiteK2500!

You're welcome.

Peter and I are thinking about making these into kits, so it'll just be an install deal, everything will be prewired, soldered, and all solder connections, heat shrunk wrapped.

The problem, as with getting anything started, is the funding. Money is tight, specially expendable money

It's not hard to do at all, but I know there are some people out there, who just can't be bothered to make the kit, but would gladly install it, and love having it.

Terminal Pin 12089649 Pics

I took some good pics of the terminals I bought. I've used one already and so I know they are correct.

You can look in my garage - the Other Other 6.5 garage - for the same pics.

Look up Kussmaul Electronics Co. They make eqipment for emergency vehicles. They have high idle kits for mechanical pumps that will fit nearly anything.
I had a high idle switch on my 89 6.2L Chevy too (not a Kussmaul, though).

Thanks for the great write-up & pics. I put mine in last night -sure beats the Stanley Wonder Bar beetween the t-case shifter & pedal.

I think I have figured out how do in theory. Will have to wait until I get mine on my truck to implement it.

BUT....does your truck have cruise control? I bet we can trick the CC module into thinking the truck is in gear......

I don't know about the pre-OBD 6.5L's, but (some?) 6.2L's have a high idle solenoid on the pump, and all you have to do is run 12v, through a switch, to it.

I just got my high idle installed, very easy to do. I finally was able to order pins at the dealer. I also put a home made winter front on, I'm curious to see how much quicker it heats up.

I have 6 spare pins so if anyone needs them just pm me, first people I hear from will get them.
