American Autowire Rear Tail light Harness

[BC10]

I just received a rear tail light harness from American Autowire for my 68 Stepside, and had two questions.

1. I don't see a connection for the rear side lights that attach to the side of the rear fender. Did the stock 68 C10 have blinking tail lights when turning? Stayed lit all the time? Or were just reflectors?

2. Should I have ordered a 69-72 rear tail light harness instead? Do they include an extra wire for the rear fender side lights?

Thanks!
