i dont even know if its accurate. and what does stoich. mean?

 

i would assume red is posative. Black is ground... purple is to the O2 sensor

 

Stay away from the O2 sensor; wire it in at the ECU. You can make all three connections there.



S4 right? Red wire to pin 3I, purple wire to pin 2D, black wire to any one of the four ground wires, or put a ring terminal on it and put it under a handy bolt.

 

Nooooooooooooooooooooooooo!

 

No what?
