I need help Identifying a couple wires.

So, its 54° outside, dark, and with Monday night football and a cold beer calling my name, I'm going to call it a night. Here is a picture of exactly what i have done so far. Following your advise, I added a second wire for red. It only took a few mins.



I am wondering if now is the time to take care of the cluster voltage regulator since i already have the cluster out. Mine works just fine, but rather safe than sorry?? lol

On the wiper switch. The whole back side of the switch pulled out rather than the connector coming off. Any chances i can just pop it back together?
