battery disconnect, car crashed killerbee only cut engine after crash

[new-fg-owner]

just ordered a superbee to go in the contrast neox. update on the killerbee v2 on my FG it works fine if i don't use the 2nd channel throttle failsafe. i've realised i think how to attach the oddified ECU red and black cable to the killer bee, just solder the the red to the red cable n black to black cable going from killerbee to the the red killswitch button on the engine.
