Looking for info on how the wires were originally ran. The original wires are taped together with electrical tape and are a mess so I am redoing them. I have a dual filament bulb so their are two wires. Did they lay loose in the wire holders? Was there a sleeve over them? Were they bound every so many inches? I have peeled back some electrical tape and see what Looks like a 3/8" fabric tape binding. Any help would be appreciated.
