[QUOTE="Fred W, post: 1231802, member: 3828"] Grounding requirements depend somewhat on what you intend on powering with the power distribution block. If all you are powering with your fuzeblock will be heated gear and the like, then you can just make a good ground connection anywhere on the frame. I just used the seat latch stud/nut for picking up a ground for powering our heated gear in my [URL="https://www.fjrforum.com/forum/index.php?showtopic=141482"]Frugal Yankee PDB[/URL]. OTOH, if you will also be powering [I]sensitive [/I]electronic or audio devices, conventional wisdom is to run a dedicated large gauge ground wire all the way back to the battery. I say conventional wisdom because a long unshielded ground wire run through the engine area can actually pick up more ground noise than just grounding to the frame, which is a giant conductor itself. Also, some electronic devices (many GPSes for example) are relatively insensitive to ground quality as they have a regulated power supply that is only used to charge the battery that the device runs on. That provides some isolation in that regard, but the audio output on any hardwired cables may pick up noise from the ground wire. Bluetooth audio should be relatively unaffected. [/QUOTE]
