Default Headlight wiring question

As I patiently wait for my Electrical Supplement to show up, I thought i'd at least ask the question. (my headlights turn ON, but not UP)
I re-installed my headlights and connected a single wiring harness to each. When I received the car (bought at auction) there was nothing plugged into that small wiring harness on the driver's side in front of the front tire. (it should be noted that it was hit on that side!)
Am I missing a connection? The lights come on, but won't flip and I don't hear any of the "electrical noise" I keep reading about on this site.
My next stop will be the relays to see if maybe there's just no juice getting to them....

Thanks for your input!

I have a 1990 elec. manual working from the headlamp door motor back check for power!

You have a (left side) gray/black and dark green/black wire.) Right side is gray and dark green

From there it goes to the headlight control module. (solid state) from module you have 2 red wires (hot wires hot all the time with fusible links and a black wire for the ground)
fusible links ( Link f and link g) and a yellow wire ( goes to headlamp dimmer switch) and a white wire ( going to the light switch ) that is hot all the time also. (clear as mud huh) Dont know if this helps.
