I'm guessing that the 470K resistor is to drop the pot loading value in half for the split and parallel positions?
For me, I like to break down what connections exist and need to connect in each scenario. So first we have 4 wires. Green, White, Red, and Black. The Black wire is the Hot wire and the Green is the ground wire typically. If you want the pickup to work in series you simply attach the Red and White wires together with the green to the ground and black to hot. I'm going to use G, B, W, R from here on out... For parallel, you connect the G, W together connected to ground or hot as desired, and the R, B wires to hot or ground as desired, so long as one pair goes to ground and hot. For split, you typically just use the G and R wires or just the W, B wires. The switch you have is actually a DPTT ( double-pole triple throw ). It has a weird switching layout that is not intuitive if you don't probe it out.
The connections look like this:
You have a type 2 switch most likely. So disregard the upper Type 1 connections.
So with the switch in the down position, the G and B go to ground and the output respectively, and the jumper that goes from the center of the switch to the upper lug connects the W & R together. This is series. In the middle position, the G and B wires again go to the ground and the output respectively, but the W & R wires get tied together with the G ground wire. This creates a Split coil where the effective output you get is the B and W coil. The G & R goes to ground shunting that coil altogether. In the up position, the G & W are connected to the ground while the B & R are connected to hot. This is a parallel connection that is noise-free. You can wire it another way to be parallel and not noise-free, but that is for another post.
The unfortunate thing is that you do not have the ability to add the resistor and be able to switch it in and out with the switch you have. You need a TPTT switch to do that and the wiring will be totally different as well. I am also not 100% sure how you want the resistor placed in the circuit? I assume you want it connected to the hot lead to ground. I presented this wiring diagram so that you can see why it was wired the way it was and why it won't work.
