I read this in the relay section...
The coil of an SPDT or an SPST relay that we most commonly use draws very little current (less than 200 milliamps)
Also this...
A single output connected to multiple relays will allow you to open continuity and/or close continuity simultaneously on multiple wires.
So I'm currently using my 250mA GWR output to trigger a relay that forces my truck's blower to high when remote started. I want to add another relay to turn my radio ignition wire off while remote started. Can I safely trigger the 2nd relay using the same output or will that overdrive the GWR output and burn it out?
Thanks, Steve

Basically I'm wondering if the relay needs close to 200mA to trigger or significantly less, and roughly how much does each relay draw just to trigger it?

A typical Bosch / Now Tyco draws 160 milliamps. Make the alarm trigger 1 relay and make it trigger the 2 relays you need.
