Hi there, just wondering what the purpose is of the small vent that's to the right of the steering column on the dash, to the left beside the trailer brake controller as pictured, is this a speaker or a vent for something. Just curious

 

Don't know. Wondered myself. What can you tell me about your boost gauge set up?

 

Not sure but would guess its a port for a buzzer or speaker or something.

 

Its for the ac or at least that's what I have been told.

 

That's the interior temp sensor.

 

Magnus,
This is not my truck, it's just an image from Google as I was too lazy to take one of mine. Nice gauge though, Sorry!

 

lets get a real answer for this question...

 

They've had these vents since the 90s.. and we've always wondered what they ate used for.. never got a legit answer tho..

 

Roush sells a boost gauge and holder on their website.

 

Thanks. I guess I should say I was curious about what brand his gauge was though. It's not the roush or any other brand I've seen before.
