I'm sure theres a product out there that'll do it better than this method.
You might want to search around for "analog to relay control"
There are RPM switches available that switch off the engine speed instead of the throttle position, just set the RPM switch slightly above idle engine speed.
MSD makes one. Typically used to replace the VCT function on RB20 nistuned ecus on RB25 engines.
If your throttle body has idle/WOT switches like a Q45 throttle body then it becomes trivial just wire a relay to be on when the throttle body is not at the idle position.

Im working with the blacktops TPS sensor, so it will work the same as the q45, right? Im looking into it right now.
EDIT: Think i found what you are talking about. Will work just perfectly for my setup. Thanks for the help, both of you!
