came with adapter cables but one of them only has 3 wires going to the 4 prong sensor other one has 4. question is which goes on manifold and which goes on charge pipe? thanks! and yes im getting a tune b4 i drive it at all lol

 

i have no idea why i posted this since ones a 4 prong n ones a 3 prong connector..... lol

 

they will only fit one way

 

i noticed that lol idk why the stock ones have 2 bolts n these only have 1 its kinda strange

 

Who knows, it works lol

 

Look at the engine harness, one will have 3 wires, one will have 4.
