    HBP Upgrade

    Hi all, I have made myself a new HBP to replace the one on my CTC printer
    New HBP as 4 wires coming out of the mat (130watt) 2 are for power +,-
    and 2 for the Thermistor (Item is this http://www.ebay.co.uk/itm/2813982211...%3AMEBIDX%3AIT)
    The old HBP as 6 wires coming from it 2 For the power for heat and then there are 4 other wires labled Sig, Gng, Gnd and 5v.
    Am I correct in saying that I can put the 2 Gnd wires to the alluminium bed (1 off the fixing bolts I have made) and the remaining 2 to Sig and 5v or am I completely wrong.

    Need help please
