Zex nmu 2011+ 5.0
I have a zex blackout kit that I am "attempting" to install on my 2013 5.0. I'm having an issue programming the nmu. Everything is wired correctly. There IS 4.5vdc present when I open the TB by hand. I pressed the button to place the nmu to put it in teach mode (red led) then go to the peddle and hold it for 10 seconds like the instructions say. At this point the led should flash red,green, then off. YEAH IT JUST STAYS RED! Driving me NUTS! Anyone familiar with this set up?
