Ok...so the next spot may get some frustrated but this is going to help you out quite a bit. It took me a bit to figure out but once I did, hell, it was easy.
To remove the ground you will need some kind of small, very tiny screw driver or thin punch awl.
This pic shows what needs to be depressed to release from the housing
This pic shows were it is in relation to the housing. Once you hit that retaining clip dead on it will just slide out with a very gentle pull. So if it's not coming out gently you haven't done a thing to release it
Once you got one done the other side is the exact same thing and exact same wires and even the same colors.
Note prior to re-assembling entire. do a quick mock up and loose assemble to test lights before you start to bolt down anything.
Here are some troubleshooting tips:
once assembled and you turn on bike to test lights and........
The taillights comes one but don't blink......you have the terminals reversed. Just go back to the step where you push it thru and flip it 180 degrees.
You hit right turn signal and left one blinks........well I think if you done this much you'll know exactly what to do at this point.
Hope this helps someone to tackle this job
Oh the front is the exact same
