I guess my question was more voltage related. To get the 12v to run to the switch for the lights do you have to use a 36/48v source, step it down to 12v and run it back to the 12v pole on the switch or is there a 12v source on the cart?

Any two of the 6 volt batties will give you 12 volts

I understand that, but it is my understanding that when parked turning the run/tow switch to tow with eliminate or minimize any static discharge. Wiring directly from two batteries would bypass that. Is there another 12v source in the cart system?

Some use a separate 12 battery while others use a voltage reducer to step pack voltage down to 12 volt. Either of these methods are preferred over using 2 of the batteries, so as not to put all the drain on just 2, instead of the entire pack. The closer you can keep all the batteries state of charge the better for battery life .

There are essentially three ways of getting 12V for accessories.
* Use two of the 6V batteries in the series string.
* Use a 36V (48V - or whatever) to 12V DC to DC converter.
* Install an auxiliary 12V battery to run the accessories.

The 12V can be ran through a Off/On/Lights type keyswitch or through a separate switch or switches of your choosing, that you install.

Some people construct very elaborate power control panels for accessories, others use very basic ones, the variations are pretty much limited to your imagination and financial resources.

Technically, the second single pole can be whatever voltage you want or need. I wired mine up to power a 36 volt relay, which provided power to all of my accessories.

Is this the switch we are talking about?

I bought an OEM from shopezygo.com, but any make will work. Look for a three position outdoor rated switch. Uniquely keyed is an option, but costs a little more.

Thats a **** cheap price for a unique keyed 3 position switch. I cant get them for that price wholesale.

The switch linked above is for the fleet key switch SKU 3369G01. The unique key switch is SKU 3369G03 and is about $30 more.
