TPS mod on DIyPnP
 

right now there is a resistor between TPS and VR-

I understand I remove this resistor.
Then run a jumper to my TPS signal pin from the TPS solder point.
I also need a gnd jumper.
Then do I use the solder point marked vref near the "boot" section of the board. Or do I use the VR+ two holes to the right of TPS?

Dunno what your on about, vr+2 is for vr input conditioning, but to fit a variable TPS, remove said resistor, then wire gnd, tps sig and 5v vref to the corresponding pins on the tps.
