Trying to figure out where the brake light switch (if it has one) is located. I see a box on the crossover that looks similar to AMU on Freightliner. Is one of those the box for brake lights? If so which one?

Should be under panel behind clutch pedal. They usually have labeled tags on them.
Socal Xpress Thanks this. -
I found several air switches but none have power to them. I checked all of the fuses and relays and all appear to be fine. The ones that I think might be for brakes were marked E1 and D1 (if I remember right) But none had power to them. There was one that had brake on it and we replaced that one with another air switch from a different Volvo but nothing.

if you look on the firewall, there is a 1/4 line coming in blk hose other side of it is the SLS switch or look on the inside of the manifold for SLS written on manifold.
Smellfunny and 062 Thank this. -
They took it to the dealer. Will find out what it was hopefully. They said it would be two weeks.

LOL Well that truck went to Volvo and they said it was the brake light switch. Same truck is back today with no brake lights to just the trailer this time. I hate dealing with Volvo.
