Assuming the wiring colors are the same for the lighting on 2001 and 2004 rangers, this should be the easiest and safest way to do this. You need to wire a 30 amp relay off of the dashboard headlamp switch to the low beam wire off of the column mounted multifunction switch. Ground one side of the relay coil and connect the other side to the Red/Yellow wire off the dash switch to trigger the relay when the switch is turned to headlamps. Take the normally open contact on the relay and connect it to the Dark Blue/Orange wire on the dash switch, with a 20 amp fuse in between. Leave the normally closed contact unconnected and connect the common contact to the Red/Black wire off of the colmun mounted switch. Cut the Red/Black wire between the column switch and where you made the connection, to prevent back-feeding into the switch. This will turn on the headlamps whenever the dash switch is turned to headlamps, regardless of the position of the column switch. If you'd like a wiring diagram email me at firstname.lastname@example.org
and I'll do my best to get it to you. Hope this helps.
