EZGo Express s6 electrical accessories

[randyh]

Hello All, I have an interesting electrical project I am hoping someone can help on. I have read similar posts but I seem to have one different issue. I am trying to add a ton of 12 volt accessories to my EXGO Express s6. I have all of the accessories ready including voltage reducers and fuse blocks. The problem is that I want all of them to be locked out when the key switch is off. On the Express, the Key switch only has 12 volts to it so I cant energize a 12-48 reducer with the key wire that requires 48 volts. Here is the basics

Battery to Reducer
Reducer to fuse block
fuse block to accessories.

What I really need is a small relay that will energise 48v through actuated by a 12 volt wire from the key switch. Any ideas or thoughts would be appreciated.
