My DSP2 switch showed up yesterday I just wanted to say thanks. I just have on question though why is there 2 wires for the ECM? Is it just in case one pole in the switch gets worn out?
Thanks Robert

I had the switches made universal for both LLY and LB7.
So the blue wire would hook into pin #31 in the blue connector of the LB7 ECM or the black wire for pin #1 in the black connector on the LLY ECM.

So, one could cut off the "unused" wire and pin and use it for the DSP2 "enable" wire?

Rats! I just remembered that the LLY and LB7 pins are different! Darn!

No, One wire is for LB7 and for LLY.
