Chosen Solution
I need a wiring diagram for my xl7. The check engine light came on after a garage worked on the air conditioning. he error code is the O2 heaters in both sensors 31,37,51 and 57 I think is what the codes were
@paradisejax you would definitely narrow it down if you could tell us what codes were shown. In the meantime this Suzuki wiring should get you in the right direction. It is extensive, so it will not be as easy as it would be if you had a specific code.
