The hella E codes are direct replacements, the 65/55 is the wattage 65 High beam, 55 Low beam. As for the wiring the stock wiring will work OK, better than the stock headlights unless you up the wattage to the 100W range and above, then the auxiliary harness is really needed or you may melt the wires. When doing it pick up a burnishing tool, looks like a small nail file but is the width of the socket plugs that go into the lights now, if you can find a nail file that will fit that will work too. Clean those sockets of any green corrosion, also pick up a tube of dielectric or 'tune up' grease and put a dab on the spades of the new lights. This will keep corrosion to a minimum and reduce resistance which is what causes the heat build up. This kit at the link I posted above will work fine H6054D. I have been running these E codes since 72/73 in all my vehicles that had standard headlights. I'm picking up two more sets of round ones for our two new TJ's, I want the kids to have the best lighting they can [as well as two new Warn front and rear bumpers]....
