Hey Guys,

Any idea if an Add-a-circuit will work for powering the JB4 and other devices (E82 N55)? I have JB4, FSB, and Flex Fuel Analyzer to power. I'd love to tap them all to one add-a-circuit.

Thanks,
Adam

It would work but it wouldn't necessarily be the safest thing. You'd need a bigger fuse to compensate for all three devices in the same circuit and if that circuit were to ever be overloaded and the fuse wasn't properly sized for whatever reason it could very well start a fire.

If you were to properly size the fuse and it popped one day, instead of just looking at whatever circuit popped you'd have to fish through all three devices to see what's causing the problem making troubleshooting that much more cumbersome.

Terminal fuse block off the positive post.

I've had a 15 amp add a fuse powering my JB4 when I used one in the past. Also powering ECA, port injection and WMI pump. No issues.

The V2 JB4 doesn't take in 12v power externally.
