That might be the park brake switch so the ecm knows the brake is set so you can bump the idle up. Some trucks had 2 switches on the service brake side one for the ecm and one for the brake lights. There’s 2 main types of pressure switches Normally Open and Normally Closed you can tell the difference by the height of the plastic but I can’t remember which is which.

 

I hear ya.
But, I did make my drop this morning..
To honest for my own good.... Sometimes...

 

Ha! Didn't even cross my mind......but ok I'll go with that ! LOL

 

Thanks for the compliment!
Yeah I just couldn't figure it any other way. Heck, even while spewing air the old switch was still turning on the compressor..

I'm trying to get more hands on as I go. Hard to find good honest help sometimes..

 

I know on a Peterbilt them switches come in two kinds. Contact normally open. Or contact normally closed.
Thinking about it they prolly vary in the pressure needed to move the contacter as well depending on the application.
Parts guys these days don't know or care the difference. As long as they look the same...

 

AZ is a dead zone for flatbed freight. Ya take whatever ya can get or bounce out. Unless your Cali compliant, El Paso probably the best bet.

 

Ooooh - and I got one for ya if you really want a riddle Batman -

Boils down to parts guys, and Peterbilt and Detroit . . . and a mysterious guage called "Lucky Sue", that reads your (palm) temperature wrong . . . every time.

 

34 reset time — bar o’clock.

 

I wonder how many times that's been stolen.
