69 Valiant - Electrical / Turn Signal Question

I pull the cable out and run it back in between my fingers loaded with white lithium tub grease. Pushing the cable back in can be agravating but it will go .If you do that be sure to clean the excess from the connecter cavity. Too much grease into the instrument can harm it.
Some will suggest flushing the sheathe with brake cleaner but you would need to disconnect the trans end of it.
