I added an SAE Connector to my battery to facilitate quick, easy, & clean connection to a battery charger/maintainer.

NOTE! On the SAE Pigtails I bought, The wire colors are backwards. The black wire needs to connect to the positive (+) side of the battery. The red wire needs to connect to the negative (-) side of the battery

To "fix" this, I "colored in" the red wire with a black sharpie to make it less confusing (shown in last photo only).

Instructions

Line the SAE Connector Pigtail up to the battery and cut the black wire (positive battery connection) a bit shorter
Solder ring terminals install ring terminals onto a premade SAE pigtail
Screw the new wire harness onto the battery
Optionally superglue & fusion tape a small magnet to the SAE connector to be able to attach it to the bike frame when not in use
Color in the red wire with a black sharpie to avoid +/- red/black color confusion
