Step Down Converter for Lithium 2007 Precedent
I am in the process of installing a Step Down Converter (48v to 12v) in my 2007 Precedent (OBC bypassed). I am coming from a 4x12v battery configuration and assume that there was never a need for a step down converter. Now that I have 3 lithium batteries (48v each) I need to convert 48v to 12v. I will be running the lithiums in parallel and will connect the positive and negative converter leads at the end of the positive and negative runs. My question is the accessory cables. It appears that I will remove the blue accessory wire (see attached pics) from the battery connection cable and splice it to the positive accessory wire on the converter. My question is, where do I connect the negative accessory wire coming off of the converter?

Didn't the voltage reducer come with a wiring diagram? 48V positive and negative from the battery into the reducer and 12V positive and negative from the reducer to accessories.

Re: Step Down Converter for Lithium 2007 Precedent
The accessory is the headlight/breaklights and it is connected via multi-prong connectors under the dash. Then there is a blue accessory wire that goes from a wire pack under seat to the positive terminal of a battery. So I have no idea how to run the positive and negative wires.

You should use a distribution block for the 12v positive and negative. Connect all of your accessories to that.
