Anyone know how to wire in half speed reverse?

Yes, that is the correct one for 48v and the Relay coil is the only difference for 36v vs 48v system, sorry I am not familiar with Yamaha.

The wires on the left go to the "small posts" or activation terminals on the Reversing Contactor coils.

Whichever coil has power when your Key-switch is on Reverse is the one You want to connect the new relay wires shown on the left to the positive and negative activation terminals.

You are awesome Segio :) I really appreciate the help with this, plus the lower cost benefit of your solution. I'd much rather spend little dollars than BIG dollars plus having to remove the PB-6 lol.

Let us know how it worked and which speed you used (50% or 65%)?

I updated the original post with the link for the 48v relay and the notation on the drawing as well.

I most certainly will do!

I was just getting ready to put this together but how do I connect the relay to controller #2 and #3 terminals; when I already have the PB-6 wired to those same terminals? Can you please detail this a bit more for me?

There are several ways to connect to those wires or terminals, just keep in mind two points (no reason to over do it):

It is a very low current connection.
In case of a connection failure the cart would just run at full speed in reverse.

If You run the cart through a lot of water, some options are:

Strip a little insulation from the wires that go to Terminals #2 and #3 and solder the wires that go to the reduced speed relay.
Cut the existing quick connectors OFF and crimp both wires (existing + relay wire) to a new quick connector.
Use Posi Lock tap connectors.

For all other applications since it is not a critical connection I would just use blue Scotchlok Tap Connectors in each of the wires that go to Terminal #2 and #3.
