R/S wont crank mazda6 2004

Verify brake shutdown is wired correct if its seeing a constant 12 volts it will be non responsive

that was the last thing I verified before I put everything back together awhile ago... same problem worst part is I can't even do a shutdown diagnostic--not responding but I manage to reset the RS and add remote so it means it is functional.. :(

I think what you are missing is H3/8 RED / Black from viper to BLACK / YELLOW on your car's 12v for acc/starter input. I connected all the reds from the heavy gauge from my model Viper 5706v and it works flawlessly.Honda Accord 2008 EX-L 2.4 S

I found the problem.. Pentavolvo is correct.. The diagram that was provided by the vendor is actually supplying 12 volts so I ended up tracing all the wires which it leads me to green wire (press brake + 12 volts). They told me to use the brown wire which is constant 12 volts. Also I swap the fortin bypass with the old school 556U it works like very well without cutting any wires. Customer service of fortin is really horrible... Thanks for all the help
