more o2 sensor dramas

[xLegendOZWest]

m50 nv.
e 36 harness. (auto)
i cut the auto shit out of it and the car runs good (rich as theres no o2) put good. but in my cutting frenzy i cut the o2 plug off because i didnt realize it went down to the trans.
i got another one but i dont know where to solder it back in
at the ecu? (what pins?)
or at the relay (which tabs?)

the new conectors wire colors are as follows
yellow
green
brn
blk.

what goes where?
i tried wedophones and it makes no sense to me.

thanks for the help in advance guys.
i gotta get an o2 on this thing as shes my forced daily and i dont wanna wash a motor by running too rich.

lack of O2 input will just put make the motor run on the stock maps. You won't be TOO rich or TOO lean, but don't quote me on that. I hereby disclaim all responsibility for shitty gas mileage or toasty pistons.

yes but it came with one so it should have one so it can deviate from those maps as needed. due to different air densities etc.

There is a sheilded black cable with the 4 wire colours you mentioned in it coming out of the ECU plug. Looks like a thick black wire, but actually has the 4 wires mentioned in it. solder to them MAKE SURE THE CONNECTIONS ARE GOOD AND THE SHEILDING GOES OVER THEM! Or else you run the change of the car running like balls because of interference.

Kinda related, does this use the same bosch 4 wire O2 as an m20/mustang would?
