1969 K10 Cigarette Lighter Wiring

[ekneen]

I'm in the middle of rewiring my '69 K10 and have hit a snag at the cigarette lighter. See image of back of cigarette lighter, which has two old wires headed to it (one to the center threaded post, the other to the offset component). The AAW harness just has one orange wire with a very different connector intended for the post style. Advice? I'm not relying on the old wiring or components being original as it was a mutt of a truck and the wires leading to the old cigarette lighter were multiple frayed wires daisy chained in series.
