Default Throttle return springs for a sprint event

I'm doing the VSCC Pomeroy Trophy at Silverstone in a few weeks, a sprint with other cars on track (some of them vintage cars), with each car having a target number of laps to complete.
http://www.vscc.co.uk/page/events?eventID=1098

It is being run under roadgoing series production car sprint regulations but some aspects of circuit racing regs also apply, and I just want to make sure I won't get turned away at scrutineering.

MSA Blue Book J5.4.2 says there must be a mechanism to positively close the throttle in the event of a failure in the linkage - would there be one as standard on a blob WRX engine? Looks like there are two springs in case one fails, but I also seem to have two places where the throttle cable could go, so not sure whether one is a failsafe or acts on the other linkage... anyone? Seems like a simple question but I'd rather look silly now than after driving to Silverstone!
