Put a Ramtech fail safe on my XT, not sure what you could possibly do wrong basically you only have 2 wires that hook to the motor and 2 wires that hook to the push button switch and the end hooks into channel 3 on the receiver, after doing this my truck will not start will not even attempt to start like it has no spark, I guess I will take the Ramtech back off and see if it starts. Anybody else had this problem
