70 Mk III - I'm trying to directly wire +12v to my dash board lights through an aftermarket potentiometer/switch.

If you follow the path for 1 and 2, and 3 and 4 they all go to the lights for the gauges. If you ohm them out, there is continuity between all of them. I hooked a +12v test source to #1 and #2 and the lights worked.
On the plug that fits into the socket:
#1 has a small red w/green striped wire
#2 has a small black wire
#3 has a thick green w/black striped wire
#4 is a small black wire
So my question is, how do I wire this all up? I'm not a electrical engineer, so please keep it simple.
I was thinking of cutting all four wires to the socket, then hooking #1 and #3 together, and #2 and #4 together (grounds?).
Then hooking the #1 and #3 connection to the voltage from the potentiometer, and the #2 and #4 to ground. Is this right?
