Please help: High idle wiring problem, working on it now

[Glock-9]

Hello,

I attempted to do the high idle mod today with no success.

Here is what I did:

I connected wire 322 (lt blue yellow strip) to the "power" post of the toggle switch
I connected wire 294 (white/Lt blue strip) to the "acc" post of the toggle switch
I connected a ground wire to the ground post of the switch

When I turn the truck on I do not get anything. No power coming from wire 294, and no light on the toggle switch

I read the directions on the dan.prxy site and it said "when 12 volts is applied to wire 322 the high idle is activated" so i disconnected the wire from 294 and connected the "acc" wire from the toggle switch to a keyed on power source. When I turned the truck on the fuse blew. Still no high idle.

What am I doing wrong?

Thank you in advance.

Anyone? I know plenty of you have done the high idle mod, someone has got to have some input?

Please and Thank you.

For testing purposes, don't ground the toggle switch. Yes the lighted switch won't light up, but that's not the issue right now. You need to make sure that you have the wiring correct.

I would just connect the wires directly, for right now, and see if you get anything. That's a sure fire way to tell. Make sure your foot is off the brake and set the parking brake. If the high idle starts, then you have the correct wires. If not, then your wires are not correct or you blew additional fuses when you applied ground to the positive wire.

I'm guessing you are using a cheap autopart store toggle switch... That may be the problem too. Those things suck. I suggest something like this:


Good Luck!

When i get home I will connect wire 322 to wire 294 while it is idling and see if it revs to 1175 to 1200ish. Im under the impression the park brake does NOT have to be applied to achieve high idle.

I forgot to mention: While I was troubleshooting I did put a test light on the wire 294 and was not getting any voltage. That was why I connected 322 directly to a switched source. (Does 322 and 294 HAVE to be touching in order for the high idle to work?)

Once I did that and the fuse blew at the swiched point was where I stopped and went inside to make this thread.

Yes the toggle switch im using is fairly cheap. Its a stainless steel with green LED. Nothing too special but since the amperage is nill I wasnt nervous about using it.

you need the parking brake on for the mod to work.

Ok, thank you for letting me know. Ive read conflicting posts on multiple forums...but thats the nature of the beast with forums..

I connected the two wires today. Nothing. Parking brake on, truck running at idle, touch wires and not a damn thing. With or without the switch I cant get the high idle mod to work.

Any other advice?

You'll have to track down a maxi fuse or relay for the PTO now. I don't know what is used in your year truck.

I do not have to have the parking brake applied, i think 05 and up need p-brake applied there is a fuse in that circuit from what i remember.

Where does wire 294 go? That thing is so well hidden above the OBD-II port and behind the dash.....what a PITA. If its connected to a fuse somewhere (i hope) im willing to try that. If not then im going to give up.

What a bummer deal.
