I ran into this problem on my bee a few years ago and finally figured out my three prong wiring harness plug was so heat hardened it was not plugging in correctly,got one from mopar junk yard,same problem,no one made new ones at the time.Wired each wire to prongs seperately using typical wire crimp connector(tube type)crimped just enough on prong end to make tight like won`t never fall off.Works great,I was getting ready for texas car inspection.Back up lights are checked.Would of liked to have factory end but was not to bee
