Forgive my ignorance on the 2011 and newer wiring and such, but did that portion change from the CFI-4 generation? Reason being is I no longer have the OEM kill switch or throttle block on my 09. The instructions I got with the throttle block from RSI had me cut the grey wire to remove the TSS feature from my sled. If Poo changed it in 2011, then this obviously won't work.
My sled runs perfectly fine with the TSS completely removed and the wire cut.
They are different. I didn't have any problems doing what you did on my dragon, but i had to get creative on my PRO when I tried the same thing. I had a thread on it way back when, but I haven't done a search for it yet to see what I came up with. Its gotta be just tapeing closed as said earlier, but I'm positive you can't just cut it or get rid of it all together on the pros.
