Multiple devices on singular Auxillary ports

Hi all,

Just a quick question as I iron out some final details on my latest loom.

Excuse the noob-ness as always, but only one way to learn!

Let's say I have 3 fuel pumps: A 1200hp main pump (made up of x2 pumps), and a single 600hp lift pump.

Am I able to wire them all individually as far as the power side of things goes (separate relays where necessary of course), however, ground them all to a single Auxillary output and control them as one, to prime and run together?

Cheers

1 ecu output can easily trigger many relays as one.

I do prefer a single large relay though, and likewise a single fuse at least for the main pumps. That way if it blows or fails...the engine stops.

If you have safety features in place to ensure a lean condition cannot occur if one pump were to stop for whatever reason, then 1 relay/fuse per pump would also be a safe option.

Thanks Steve,

Good to know. We've got safety measures in place, as I had originally thought about a single relay for that exact reason, but decided against it. So x2 40 amps and a 30 amp it is!

Cheers much.
