hi guys im in the middle of finishing my 1500 rcsb lb7 swap and the electrical is kicking my butt. Im getting a p0612 code and cant figure it out. I heard there is a ign relay mod to fix this. If anyone knows about it help would be appreciated
That code is because the ignition 1 relay for a gasser is triggered by the ignition switch, in a diesel it is triggered by the ECM to power the FICM. You either have to use a diesel fuse panel, or you can install a separate relay outside the current fuse panel for the ignition 1 relay, and set it up to be triggered by the ECM.
