DRZ400 Auxiliary 12 Volt Power Feed

The standard DRZ400 wiring loom does not handle running high draw accessories (eg heated grips) from the ignition accessories circuit. Not only do the accessories wired up in this manner suffer from voltage losses, personal experience has seen the power connectors fail as a result.

The best method for reliable accessories power that is free of voltage losses and power connector failures is running a separate feed directly from the battery. What gauge wire selected will be influenced by what accessories you are running. Personally I go with 12 gauge with quality terminal crimp connectors and while this is a little overkill, it will certainly ensure this issue will never happen again. This has proven to be reliable and provides high draw accessories with a reliable, constant lossless power supply.
