My 87 t2 o2 senser wier got burt off by my turbo n I for got what wiers did it conect 2?

 

It's a single black wire that runs out from under the UIM, near the firewall. If you can't find it, you can run a new wire from the ECU. Download the FSM and go to the fuel and emissions section, then "control unit". It will tell you which ECU pin you would need. I want to say it's 2I, but double check it.
