I'm having the same issue for several corroded connectors in the engine compartment. I'm looking for 0.312" flag (90 degree) female quick disconnects that are insulated. So basically I am looking for the ones on this page that Timmy2 suggested, but I also need insulated sleeves, which the company does not have:
Motorcycle Flag Terminals
Any suggestions on where to purchase? I feel like i've tried everywhere including places like Digikey. Any input would be much appreciated.
