The "green ended" one is the ECU check wire - ground it, turn on the key - get trouble codes. the other is the ALDL (Assembly Line Data Link) connector - this is where the ECU's programme is dumped into the bike on the line - and where the diagnostic tool interfaces with the ECU.

Dan, I printed the codes on a card, laminated it and tucked it into the fuse box.
Most ECUs, cars and bikes, you just disconnect the battery for a good 15-20 minutes and that will usually reset the codes.Scottie
Not the case with the UCE. It stores the codes until they are erased with the Factory code scanner - which no one has. The ECU will display the codes set from last to first with no repeats. Also a code "41" is USUALLY a rotten ground in the system - NOT a bad injector. It's a pretty common code to come up .....
