i am currently wiring up a fuse box for a project that is running Fueltech ecu and dual wide band modules.

I cant seem to find the current draw for my wire sizing.

Is a single 16awg (MIL-W-22759-16) enough to supply power to both wideband modules?

Thanks

Yes. We often use 18-20 awg each.

Thank you

To be more specific I tend to see ~.8 amps draw on LSU 4.9s. Initial inrush when the heater snaps on is usually around 3 amps. This is using motec gear and heating strategies. On this specific vehicle: pdm15, M600, onboard o2 controller.
