wiring igniter on to coralive ballast

[mike31154]

It's a bit risky to provide advice on wiring ballasts at the best of times, let alone trying to do so with the limited info you've provided. I googled 'Coralive' and got hits on various 'Coralife' fixtures but even with that, not knowing a model number or what size, brand, standard your ballast is makes it near impossible to provide useful advice.

Fixture manufacturer (spelling can be important here) & model number?
MH lamp wattage? 250? 150? this will aid in determining ballast spec.
Single ended or double ended lamps?
Probe start or Pulse start, with ignitor I assume pulse?
Ballast brand/type/model/spec, i.e. M58, M80?

If you're able to at least provide the ballast ANSI code like M58, M80, it would be fairly easy to find the appropriate wiring diagram.
