Here's another set of instructions from dieselmanor for the TS chip.

Hmmm, same chip but different instructions. They indicate to reinstall the gold ground tab and also state that the black plastic needs to not be cut out and that it is there to hold the chip in place.
I don't know. I don't want to screw this thing up and I can follow instructions.
