picked up a 2007 txt 6 passenger shuttle - wiring diagram?

[ycis]

so i scored a factory 2007 ezgo shuttle/people mover today that is going to be my next project (have more kids, need more seats!).

its clear from driving it that its a sepex/regen cart with 8 6v batteries in it for the 48v pack.

what I cant discover (or at least didnt in my going over the system)...is some sort of built in reducer (or even an aftermarket one)? Clearly the cart has numerous 12v features on it (many of which need replacing, but im betting this is more corroded connectors than anything)....including head/taillights/blinkers, horn, 12v blinky/flashing light on top (kids favorite part sofar, guess it was a security guard or parking lot cart). while i can see a very old fuse panel (uses tube style fuses vs blades), i couldnt or didnt find any actual obvious reducer of any sort, and it certainly didnt seem to have any 9th 12v battery that i saw anywhere.

do these carts have some sort of built in 12v reducer since they were designed from the factory as people movers etc?

anyone happen to have a location for a wiring diagram for the 6passenger carts? I certainly didnt expect to see the controller and the noid under the front seat, vs having it all stored where it normally would have gone in a factory 2/4 seat cart!

thanks in advance!

ps. also anything i really need to know about sepex drive carts and such? shame after all the time and money i spent rebuilding my old series txt that none of that transfers over!
