Most of the time it's visable.That is an ohm meter correct? I am hoping it just a ground wire or something. Thanks!!
Man you can fix anything with a new chip!One option to fix code 43 is in the PROM programming. Might not be the best option, but it will be a permanent fix for a code 43 from ever coming on again.

The custom PROM chip you have Does Not use "Burst Knock Retard". I really did not delete the EGR, the EGR will work should you ever decide to drive 255 MPH.
