Hi Guys,

Just found this site. I like it.
I just transfered my Western MVP from my 2000 F250SD to my New 2003 F350SD. I have one problem. My plow lights do not switch on, when I plug the harness in. The plow works fine. I changed the two relays and no change. I jumped the wires to the lights and they work. Anybody have this problem before?

Thanks for the help.

Yes, The truck lights stay on, will not switch to plow lights. I have jumped the relays and can get the plow light to work. There is a brown wire that goes to both relays, that needs to send power to the relays in order for the relays to work, but I don't know were it suppose to get it's power from.

Power For Relays

You need to tap the brown wire into the park light circuit so that power is supplied when you turn your lights on. The ground is picked up when you plug in the harness to the the plow,turning the relays on.:rolleyes: John

Thanks for the help guys:waving:

I started to think were they pick up the parking light circuit. It was a poor connection at the LF marker light. Fix that and the plow lights work.:D
