Thank you, gentlemen, for your help. I just came in from cleaning up the drifted snow by the light from my newly wired headlights
! Ron, as you had advised me in another post, the 4511's fit fine. Not much clearance though between the terminals and the metal housing, so I covered the connections with liquid electrical tape to prevent shorting out. I don't know if that was a good idea--I know almost as much about wiring as I do about women.
I ended up using red 14 gauge wire which I ran to both sides to match, although Jim was just right, the left side would have given me plenty to rewire the right light. Bigdog, I checked out the AgriServices link and called them this morning. I ended up ordering a whole harness from them. I looked mine over carefully and it's pretty shabby in places. I'm going to be rebuilding the touch control unit shortly, so it will be a good chance to rewire it then. Thanks again for the help.
