I'm installing Isspro EV gauges in my truck, and need some electrical help here. My pyro came with the signal amplifier box which needs a power feed. The directions say to use ignition-on power. I grounded the black wire to the dash chassis and ran the red one into the fuse panel, hot side of #16 (spare). I was thinking about it, and there is no fuse in here. What amp fuse should I run inline?
I've emailed Isspro, just wondering what everyone else has been doing. BTW, I'll post their reply when I hear back

 

I installed a Painless Wiring 7 circuit fuse panel (4 Hot with key ON - 3 constant Hot) to handle the load of my aftermarket accessories without resorting to 'tapping' existing fused circuits.

 

Do you have a signal amplier box with your pyro...what size fuse did you go with?

Fuse #16 is open and un-used, so I took the easy path and used it

 

My Isspro Pyro also uses an amplifier box.

I have it protected by a 20 amp fused circuit, hot with the key on.

 

Just got this from ISSPRO:
"Normally these would be connected to a fused circuit. A 5 to 10 amp circuit would provide plenty of protection for the EV gauge amp box."
I've been running for a few days with the box connected to a 10A fuse in slot #16.
