That's great information, but unfortunately all of the wires on my harness are black
Oh yeah, forgot about that. The wires on the engine bay harness are colored, but the glow plug harness itself is all black. I'd grab a continuity tester, poke one end into the pin of the glow plug harness connector that goes with the red/white wire, and use the other end to figure out which glow plug connector/boot it goes to. That should be for plug #1.

Someone on the facebook group mentioned that sometimes there is "a bit of white tape wrapped around one end. That is #1."
Mine is no longer white, but there is definitely some sort of tape/label looking thing on one end so I went with that.
I don't remember seeing tape on mine, but I believe if you install it with the wires above the glow plugs (i.e. closer to the intake manifold), that should give you the correct orientation. Assuming someone hasn't previously twisted the glow plug connectors around to face the other direction...

So #4 is the one closest to the firewall?
Yep, #4 is closest to the firewall and #1 is closest to the radiator.
