Replaced the switch this morning and all is good. Thank you for the help.

Found the switch but won't be able to get a new one til tomorrow. I'll report back tomorrow with the results. Thank you.

I have a 2012 Mack CXU612 that, when put into reverse, won't light up the R indicator on the dash and neither the alarm nor the backup light comes on. I've checked fuses on top of dash and on firewall but no luck finding a bad fuse. On my fuse diagram it shows a reverse signal relay installed behind the IC (instrument cluster?) but I can't find it. Any help?
