theexbrit Posted January 27, 2014 Share Posted January 27, 2014 I need to do the wiring harness mod as I'm getting intermittent p0156 & p325 codes, I think it's the ground problem discussed here & before I go buying o2 sensors, etc, I'd like to try this. The links are all broken, does anyone have the TSB &/or photos of where to mount the harness? One post I was reading on another forum the guy said he used the wrong bolt holes & it didn't help with the problem until he used the correct bolt holes on the manifold.
