Hello,

Last night some thieves sawed the catalytic converter off my 97 4runner . Unfortunatly thats not the worst part.

When they were cutting they sliced off a piece of the manifold pipe which is friggen impossible to replace.

Anyways, I welded some flex pipe in it's place and did my best to attach it to the manifold. It runs well, no leaks & there is just a bit more noise at idle. It definatly has more pep and accelerates faster.

Moving foward the real problem Im faced with atm is the precat 02 sensor they took with them. Im left with a sliced up wire (it has 4 wires) so I really need to get my hands on an 02 sensor diagram

A diagram of the wiring scheme is my only hope because there are 4 wires. I really dont know what color wire goes where.

Any help would be super appreciated.

P.S. I know, I know it's illegal & worse, hurting the environment. However if i put it back on I will be worrying about it wherever it gets parked. So for now, im running with it (no pun intended)

Cheers!

 

Put a new cat on for the reasons you listed. The environment is important. Good luck.
