Does your truck have a Glow Plug Controler or a relay?

When this all started 6 years ago, I got a reading of #1 glow plug faulty. I went in replaced it, looked at it and it was fine. I put it back together and then it told me #1,3 & 7 were bad. I knew it was false read. Let it go drove it for 90,000 miles all good. California says have to smog, so I disconnected TS performance chip, changed GPC $220 New glow plugs, and glow plug harness, valve cover gasket. Truck starts and runs great still bad reading p0677,p0673,p0671. Why not the # 5? What about the wire harness from Valve cover to wherever it goes? Thanks Gary
