Well I got the locking mopar cap this morning. They gave me a discount at $19 bucks. So I returned the Wally World gas cap for a refund. I disconnected the negative battery cable to turn the light off. So far I haven't got the gascap light or the engine light after the new gas cap.
I think I will get the locking fuel door later on. It has a nice custom look.

I think I prefer the black to chrome.
