Nope. You ordered a front lamp harness for a '68 with separate side marker bulbs. Just like my dad's car. Very early production only, first few weeks of the '68 model year.

Be certain they are not shorting out anywhere, like the center contacts coming out of the sockets as there is no bulb in them. The factory service bulletin suggests that the wires be cut off clean near the harness bundle, then folded back and taped. Short of getting the correct harness, that's probably the best option. And you could send me those sockets and pigtails.
