I am installing a Bd exhuast brake into a friends 01.5 ho. I seem to remember seeing on here in the past that there is wire I need to buy to install into the pcm to utilize the trucks control of the brake. Where can I get that little wire to install in the pcm connector and which position on the connector is it? Or am I completely wrong about all of this.

 

I bought me Jacobs e brake used and I got the proper wire to go to the ECM from my local Cummins dealer. Eric

 

It is a clip/tab that goes into the ecm harness plug & makes contact. I never wire them in like that because the ecm will delay engagement of the brake for 3 seconds before it engages or disengages. I use a Pacbrake pedal switch which engages the brake when the throttle pedal is released. They engage immediately. The complete system on/off control is mounted on my gear shifter [stalk switch].

 

Can anyone tell me where the wire goes? Or a part number for it?
