If it worked before then it should work now. Yea, it ran with this setup, I drove it into the garage before disassembly, just have replaced all wiring with new harness etc.
If its newer production (vs. old stock original circa 1974) then only ballast resistor is used. It looks like you chose to mount the resistor on the wiper motor. I'd suggest mounting it where the factory did. It looks like a points type ballast and bracket - approximately 0.6 ohms. Those were mounted under the lip on the firewall, just above the inner fender. Pretty well protected there. I didn't know wiper motor had its own resistor, I thought previous owner had eliminated the 4 post ballast and put this 2 post on as the 4 post aren't needed anymore.
