I find that even with the new rear harnesses from year one etc only include the drivers side square socket that the crossover attachment for the passenger side not included
Yup, iirc I called them when I received mine, years ago, and asked wth I'm paying for an incomplete harness? They were of no help, probably because they just import it and bump the price up.
I recall finding larger white plastic pieces for the bulbs, but I cannot find where I got them. I image a thread on here, or possibly ebay.
