Default WIDEBAND to MS w/NO LC1 ??

My lc1 stopped working after 2 days..no signal from brown or yellow wires..
i wanted to know if anybody knows if i can hook up my wideband o2 direct to my megasquirt pnp??
i think it has a 5v rev wire for the lc1.. it has 2 inputs 1 for stock and 1 for lc1..

5 wire o2.. wires are,,

black------------vs to o2 signal to ms
red--------------ip to ign power
yellow-----------vs/ip to ??? not sure where..(help)
gray-------------htr + to ign power
white------------htr - to ground

or am i that much of a noob to think this will work..
i need to send my lc1 back but i dont want it to have to worry about it failing again..

thank you for your time..

You have to have the controller for it to work, you cannot connect the bare sensor to the MS without it.

From what I understand, the processes that the controller runs to determine the AFR's and output the voltage is pretty complex, which is why EMSs like megasquirt dont have built in processors for these. You need the controller to decipher its outputs into voltages which MS can read.
