wiring question
If you take drop the fuse box without disconnecting it at all, and look under the back flap you will find unused connections that are both keyed and unkeyed, and depending on where you make connections, fused or unfused. If you use unfused, put in the size in line fuse that the gauge folks require. you may also see connections in the back of the fuse box that are "stacked" into a single connection and you can get brass adapters that allow you to do the same.
