hey everyone, just letting you all know i made this switch and it kicks ***.
fyi i got the wire to go into the ecu from a boneyard and it fit perfectly.
only thing is that it doesnt stop when you press brake or go into a gear.

good little switch tho!

 

OB1 computers will not shut off the high idle if brake if it in gear you have to used the switch ob2 will shut off with brake or put in gear

 

oh i see it all makes sense now

thanks crazy

 

how did you put your high idle in. I have a 95 6.5 and would like to have a high idle

 

pull the glove box out
pull the ecu out of its holder
there are three plugs, pull the center one out of the ecu,
pull the 24 pin pink holder off, and then you will have a top row (A) and bottom row (B)
there is a blank space in A6 (sixth one in from the right) which is where you would put a pin with a wire into the open slot.
**THIS IS THE ECU SO NO HALF-ASSING***
i got the wire for my wire from a junk yard from the same truck.
once you put the wire in, put the pink holder back in place.
take that wire, and plug it into a grounded switch that is also wired to 12V
***PUT A FUSE BLOCK ON BOTH WIRES***
put everything back together, and wahlah
1100 RPM at the flip of a switch

you can also look on kennedy diesel, i tried to give the best directions

 

this might sound stupid but i dont want to screw something up, what are you needing to run power to and what do you need to ground

 

Here a nice write up on how do high idle switch

Do you guys have any ideas as to what to use for a pin in the plug-in

 

go to a junk yard and pull a wire from the ecu, thats the closest you will get

 

you get the pins at part store
