    2016 670. Is there any way to easily change the marker interrupt switch to flash all of the lights (minus the headlights obviously) instead of just the clearance lamps. The trailers that I pull have the clearance lamps and side markers on the same circuit... So they don't blink when the switch is pressed. It makes the marker interrupt feature useless.
     
    bbechtel16 and silver dollar Thank this.

    The easiest way I know of is to take apart your pig tail and switch the marker/parking lamp wires (phillips screw driver). My 2012 used 20amp fuses for both so hopefully that won't be an issue for you in 2016.

    Did you get a chance to switch the wires on you lights? My 06 is the same way, and I'm looking to correct mine also.

    No. I've been too busy. I did ask a ta tire changer and he said it was not very easy to do. Me and electrical wiring have never gotten along, so I'm a bit nervous to take it on... Especially if it not a very easy task.
     
    silver dollar Thanks this.

    I think this all happens through the body computer which means it has to be programmed if it is even possible.

    Thanks. Informative video; but I think I have to find it any of the leads interrupt with the switch, then I will know which ones to switch. Thanks again.

    I never thought of that. That may be the case, since there is no other reason I've seen to put an intrupt switch on a tractor, and it only interrupt the tractor lights. Maybe another way Volvo can get $$$ to reprogram it. Thanks for the reply.
