yea see im confused myself xD im just wondering how you wire everything up.

Wire the thermistor to the existing thermistor wires and the pcb heater to the existing bed heater wires. In case you are confusing a thermistor with a heating resistor, a thermistor is a temperature sensor. If you want to wire an old heating resistor in parallel with a new printed circuit board heater I doubt the standard board could handle the combined load and you'd wand to wire in a relay and separate power supply.

Your question doesnt make sense to me. I would encourage you to lay it out more clearly.
Thermistor and PCB heater are separate.
PCB heater goes to a 4-pin connector near one of the mosfets in the bottom of sanguinololu. Thermistor connectors to a 2-pin connection near top. IF you use a printrboard this is different.

Hi I was just curious on how you wire a thermistor and pcb together for the solidoodle 2 i figure you just wire them together in parallel and take the two wires solder them to a 2 pin connector but i wasnt sure if this is correct any help would be great c: i bought a pcb and a separate 100k thermistor.
