Jimmypete,
Look up "H4 (or H3) plug and play relay wiring harness". No cutting/splicing needed. I upgraded my headlights from sealed beams to Cibie with 100W hi, 55W low bulbs and a pre-made plug-and-play harness with ceramic sockets. Works great!

I also did the fog light mod where they can be turned on at any headlight switch position. I tried a couple of different yellow LED fog light bulbs from the auction site but did not like them compared to the stock bulbs. Very weak output even though the lumens advertised were high. Be cautious of chinesium junk.
