Any tips for separating the black plug, that goes to the NSS. Does the tab lift up, or press down. I don't want to break it.

Press in (down) on the tab closest to the edge of the connector. Do not pull on the wires to seperate the connectors. Like most connectors, a small screwdriver is required to coax the connector apart at the connectors split line.

If the connector is filthy, you may want to spray the connector down with CRC QD Electronic Cleaner and use a paint brush to help clean it up, then squirt some Silicone spray on the connector to loosen up the lock tab (that has been in place since Christ was a Corporal).

I use Liquid Wrench Silicone Spray in an 11 ounce spray can.

Got it apart. It was the gray connector. Rebuilt my NSS. Now I have reverse lights, yay! Inside, the NSS was pretty well gummed up. Not any more!
