ok I have searched around for this and am having an issue. I want to wire my LM-1 sensor into the stock front O2 position and I need to know how to wire it in. The big thing that I want to know is how to wire the heater in.
*edit*
to clarify what I have this is a Bosch [ 0 258 007 057 ] the wires I am looking at are black, white, yellow, red and green wires and I am running it to ecm link V3. I am told this is the same sensor used in the LM-1 kit
 
Thanks Usatuff that helped a little, so the wires are as follows;
Pump+ red
Sens+ black
Heater - white
Pump-/Sens- yellow
Heater + gray

so what are the wires on the stock sensor and can any one tell me an appropriate place to get the heater + source from?

ok so a little more digging and I get this on sensor side the wires stock are
white O2 ground
Blue O2
black and black are heater supply and ground (pin #3 power pin #4 ground)

so I get that;
white (bosch) goes to pin #4 black (stock)
Grey (bosch) goes to pin #3 black (stock)
black (bosch) goes to blue (stock)
yellow (bosch) goes to white (stock)

is this correct? and does any one know what the pump + (bosch red) wires to?
