S13 conversion wiring help

[SR20Brandy]

Hi, I have an 89 240sx coupe that I converted the front end on to S13. I am not familiar with wiring and am looking for some help with wiring up my blinkers and any other sub-harnesses that I need to make/change. I'm lost.
I also had it in a shady shop for a while where the shop owner stripped random parts on it from me so I am also looking for a tail light socket assembly (with wiring sub-harness) for the passenger side. Anyone know how to get their hands on one? I have been out of the scene for about 10 years so I'm a bit rusty on a lot of the ways to source parts and such. Any help would be greatly appreciated!
