Since I installed my air dog 150 system . I have a p0675 # 5 glow plug code and it keeps coming back. I figured it may be air to start with but now the code comes back on after code clearing. I had no trouble before I installed the air dog, any suggestions? Do you think its where I powered my fuse to the pump at? I did it by the instructions , it said to find one hot when key is on and I did to one of the suggested ones. Thanks for any info guys
