Need help fixing 458 ctek battery tender dongle

The battery tender plug that goes into the lower dash had a wire pull out of it, and I can't figure out which of the two remaining wire holes it needs to go back into. There are two wires for the proprietary plug, a red and a black. The black one is in hole 1 and the red one should be in 2 or 3 (see pics).

Any ideas on how to fix or which hole red goes in? Or even where I can get a replacement dongle (can't find one now).

Thanks, don’t use eBay anymore these days so I forget about it. Hopefully these work. I think I’m still going to fix mine so I have a backup. Much appreciated Bob!

Not sure how to interpret that except as “either one would work”. Sound correct? [emoji846]

Follow up: I purchased the charger adapter as linked above and it finally arrived this week. Didn't work at first but I had an extension cable from CTEK I was previously using. When I removed the extension the new adapter worked just fine. Thanks all!!
