starter interupt, stinger 200 amp relay

i am an idiot wrote: The coil of the solenoid is what makes it continuous.  A starter solenoid, if left energized for 30 seconds or so, it will begin to smoke.  I have no idea what current a starter solenoid is rated at, but I am pretty sure a GM starter will pull upwards of 300 amps of so.  The 200 amp solenoid will probably make it for a while.  I am just trying to figure out why he can't use the start wire at the Ignition switch.

Because it is so easy to gain access to those wires Ive already added starter interupt upstream of the remote start wire was just looking to do something a lil different and happen to have this big relay sitting around that I haven't see to come up with a good use for

part # for the stinger relay is SR200, but after taking inconsideration some of the ideas and and comments. I may concentrate on the low amperage wire, well I have a new idea(well a modified idea from a previous install), I've come up with another question, if I ellected not to use the starter kill of the 791xv but still wanted to use the auto crank, would I be able to just splice the the starter output of the relay bank upstream of my my stand alone starter interupt and still use the auto start feature? 

Yes

You'd be crazy to shove a relay oin the main battery lead all I'd need to get past it would be half a jump lead! Secondly if late model it will cause problems for the engine management.

Just realised it's probably part of a split charging system and as such there is no way it will take that current for any length of time.
