if its broken try a dab of silicone
BEST way is solder with heat shrink.... See YouTube!.... Can use solder-less crimp connectors with electrical tape... If still unsure... See mechanic!!
sorry i thought you the lock clip was broken. oops
That's what I figured... That does work good on the other end for broken connector!!
