OK! Working fine now. Thanks to all who replied particularly Mr Wizard who reminded me to use a relay. I fed a 50' 18ga wire through the grommet beneath the brake master cylinder. I started outside the front, poked a hile in the grommet and then fed a few feet of wire inside. I then sealed it up with some liquis electrical tape. I ran it down and fhrough behind the headlight. I wrapped and zipped it along the main wire harness bundle abve the wheel and back along the frame to the rear. I tapped into the yellow backup light wire at the drivers side rear corner. Back in the cabin I installed the relay (a smaller ford standard relay) and everything worked fine.
Now, while I have the dash dismantled and the seat out (only way to get to the fuses) I'll see about the climate control light with the wire that fell off and the Cigarette lighter that quit working (for charging phones) and see if I can get the map lights to work again. Then I can try to find out why the AC fan won't go full speed unless I smack the dash with my palm. Probably a bad resistor. It is not often that I get under the dash! Things do pile up! DW will be pleased.
