omega pass 4 and ultrastart 1270tl

Vehicle: 2001 Nissan Pathfinder.

The Ultrastart has an 3-pin auxillary port (GWR(-), (+)250mA 12v, (-)250mA Ground), and the Omega Pass-4 has a three pin connector: Red +12v, Green - keysense, Black (-).

Can I connect the Ultrastart GWR wire to the Omega Black wire, and the Red Ultrastart +12v (250mA) wire to the Red Omega wire?

Or ...

Do I need to provide a higher current +12v source for the Omega unit?

And..

Will my GWR from the Ultrastart unit give a (-) signal while cranking as well?  If not, I'll have to set up a relay to chassis ground triggered by the ignition wire.

Thanks!

that aux. output will work just fine as you stated. You shouldn't have to wire relays.

let us know how it goes
