Yes to the receiver and the red wire is unplug been working fine but started acting up on saturday
if you dont have a big black capacitor sticking out one end of your bec, you have an older one that alot of people had issues with burning up. ive had i think 3 of the pre-cap castle 10amp bec's fail since i started pushing my trucks way harder than i used to. they will act up and glitch, and then just stop working.
