Re: LED strip for turn signals
I added a number of LED's to my mirrors instead of using a manufactured strip. in the end, though, it makes no difference. My LED's came with about 2 or 3 foot long leads, so I clipped them to the appropriate length and then stripped the factory wires (between Honda's connector and the turn signal) as described above, being VERY careful with that razor blade - you don't want to damage the stranded copper conductors or your fingers! Twist the new lead (called the 'tap') around the factory wire (the 'run'), solder the connection and take some care using good quality electrical tape to insulate it (I use Scotch 33+). Unfortunately you cannot use heat shrink here because you never cut through the 'run' wires.
Then, use a so called 'hitachi' connector - pictured in reply #15 - to connect your taps to the LED strips. Voila, you can now disconnect the strips from the wiring harness and the tap stays with the short wires that go from the factory turn signals to a Honda 'hitachi' connector.
Flies in the ointment here are while the 'hitachi' connectors will set you back around $6 or so (plus some exorbitant shipping charge), a crimp tool might cost $20 or more, and after you ruin the itty bitty metal contact parts you will find you are now one short and have to wait to get more. If you go this route, buy several connectors - male and female, and a bunch of extra metal contacts for each half. For sure you will use them elsewhere on the bike.
Good luck!
