I'm waiting for experts to answer cause I'm learning too but those are good questions that I probably would have been asking at some point. Have you read this thread.... Wiring 25amp converter in 05' Precedent ; might be of interest. I was going to do same minus the toggle switch. My plan was to mount it all under the hood with the convertor mounted on the back of the front shock mounts which is where I think CC mounts it from the manuf and where my current 16 to 12 is mounted

Where does the factory ground run to? I am guessing the main negative terminal post... And yes, a ground is a ground, any negative battery terminal will work.

That's essentially what I am saying to do. ALL ground for all accessories and reducer to negative on fuse block. His reducer has a negative output so the main negative on the fuse block will run to the negative output (12V side) of the reducer. If your reducer has this wire, do that. I will also. But, I don't think the MadJax has a negative output wire to run to fuse block.

See this thread: Whats the correct way to wire my voltage reducer and fuse block?

That's about as close as I've found to what I'm planning...

Not sure. I have not take off the metal cover behind the batteries. The wire comes up from behind the cover. I've read and seen on some You Tube videos this appears to be main ground wire. I could just wire back to negative terminal of last battery...anybody with any experience on the 2008.5+ 6-8V setup know what this wire is for?

Ahhhhh! Got it! I just assumed (guess what happens) that there would be two negatives... one at 12v and one at 48v. Makes sense that you wouldn't need two. I'd say it's good then cause Crash is an expert!

So once this is done, how you planning to install the amp/speakers? I've been playing around with ideas in my head on this one too! Can't decide if going dash route or in a headliner. My wife says BGW has become my mistress.

I plan to squeeze shallow mount 6.5s in kick panel. May need a spacer so I don't have to dremmel battery box. Then I'm running a heahphone jack to RCA in on amp. Control sound with phone or iPod.

Now, the switched 48V in on the reducer. Where do we get that wire from?

Be careful about general comments about ground or negative, they are not all the same.
While a lot of dc-dc converts on the market share a common negative wire for both input and output, that all depends on the electronics of the converter.
Isolated type converters have a separate negative for input and output and you will either fry the converter or damage the 12v accessory if you connect the negatives together.
The documentation for the converter will show if it requires separate connections.

The factory black wire with the bullet type connector you see is coming from the B- (the other side of the OBC) negative wire. That is the correct place to plug all accessories and voltage converters. Do Not plug the converter negative direct to the battery or the OBC will not be able to measure the current being used by the converter.

As mentioned before, the factory location for the converter is on the front of the cart, depending on the converter it may already have the plugs for the factory harness.

Only use the key switch +48v for the trigger wire, do not try powering the converter from that connection.

Thanks Sergio. The MadJax only has one "ground wire" and it is listed as ground. It has a yellow input positive, black ground wire, green "switched", red output positive, and blue output positive switched.

Also, has anyone done a reducer and "spliced" into the factory harness for the lights? Or, does the blue wire from the bucket harness simply plug into the blue output (switched) wire from the reducer?

I've torn this cart apart trying to find good location, hidden to best extent possible, to mount the reducer AND amp. I was going to use the factory location at the front of the cart to mount the amp. Where else can i mount reducer? Can it be mounted to plastic?

As for the 48V+ swtiched input on the reducer, I use the wire from the key switch behind the dash, correct? Does anyone know how to determine which wire is correct?

I mounted my Madjax on the front wall of the battery box. I also installed an on/off toggle switch so I could shut down the power when the cart is stored. I mounted the fuse bar on front wall as well. The Blue Seas fuse bar I used is set up for jumpers. I have the switched wire jumped for three out lines and the constant wire jumped for three out lines. I used two buss bars linked for grounding purposes. I can shoot a photo if it will help.
