Need switch ID and placement help 199 HD police servi car

[Mdesoucey]

I recently purchased a 1966 police servi and though running, wiring is in need of replacement and looks to have been recently rigged in places.. I'm starting to rip it down and am looking for pictures that will identify switch placement . The starter button is currently on side by starter , I think it belongs on the handlebar, and there are a lot of switches that aren't operatable on my handlebars that I have no idea what they are. The siren is a pull switch located lower front box. Im also trying to figure out what the two lights are on dash, there is a green one and the other is just a hole. I'd like to bring it back to period correct , am clueless and there isnt much out there to pull from.Any help would be much appreciated.

That handlebar switch is stock and was sourced from H-D's Italian connections at the time. The starter switch should be on the right side handlebar. The entire wiring diagram and other info is in the Owners Manual, copies show up on eBay regularly. There is at least one on there now.
Ignition switch and dash wiring is the same as Big Twins.

As usual, good information from Robbie. That Rider's handbook is a wealth of information; wiring diagram, control layout pictures, specifications, etc. The Italian switch is a combination dimmer switch and horn button. It's missing the chrome cover. The other switch pictured is for turn signals. The green light on the dash is for the charging indicator. There should be a red one in that empty hole for the oil pressure indicator. Not sure what's going on about the siren. Most sirens were mounted on the front fender operating by a cable on the handlebars.
When you get the wiring diagram you can check out the wiring to see what might still be correct. You might consider getting a factory shop manual and a parts book that cover your 1966 Servi-Car. Wiring can sometimes be mind boggeling but not impossible. Be patient and good luck
