Stock 1.6 TPS on MS3/MS3x

I feel like I'm overthinking this but in Frank's guide it says "If you have no variable tps, then install a 1K resistor on your tps input wire to ground."

The way I interpret this is, "don't connect the TPS signal wire from the ECU to pin 22 on the MS main board. Instead, use a 1K resistor to connect pin 22 to a ground source somewhere on the Megasquirt."
Is this a correct interpretation? Can I just jump pin 22 to pin 8, for example (or any other of the "chassis ground" pins)?
