If you're installing the winch on a non-permanent use-by-use basis as I am, you can use an Anderson connector as shown in my installation. Once disconnected, there is no potential alternate path to ground.
If you're installing the winch on a permanent basis, you can use a typical battery disconnect switch on the
negative lead going to the winch. The only problem with that is the hassle of installing both a positive and negative disconnect switch and always remembering to turn them both off after each winch use.
I'm trying to find out 1). If the existing OE IBS is actually only rated for ~200 amps as most think it is, and 2). if so, I'm trying to find out if there are any fully compatible higher-rated IBS models.
Automotive IBS modules appear to use the
LIN 2.x serial network and, more specifically, the
SAE J2602-1 protocol. If this is true in RAM's case, then I believe that many IBS's may be interchangeable even among different manufacturers. I'll try to research this further. It would greatly help if there is anyone here who is technically familiar with LIN and the
SAE J2602-1 protocol or automotive IBS applications in general.
