[TD="class: alt1, bgcolor: #FFFFFF"]Hi ! I am new at this so please bear with me ...

This is my winter project .: Distribution Block / Powered Relay | Canyon Chasers Motorcycle Sport Touring :.

I bought all the tools however I have a few questions and hoping someone here can answer me ... thanks in advance ...

attached is the electrical schema for the license plate light ... this is where i want to tap for my relay ...

A = location is in between the side cover and the seat
B = location is under the seat, this is before the lines split between brake light and license late light
C = location is under the rear fender

questions
1. green wire is where i tap right ?
2. where is the best place to tap B or C ? B is easier however if something goes wrong it will affect both brake and license plate light. Location C is harder since i have to go under the rear fender ...

what do you guys think ?[/TD]

Back your camera up a bit.

If green wire is positive, then yes, that's where you tap.

B or C does not matter. The only thing more dangerous about B is if somehow your tap breaks the wire all together, which is unlikely if you've done it right. Otherwise, electrically it's just as dangerous wherever you put it.
 
The location that is most accessible and out of the weather, if that's possible. Perhaps at B you could just solder in one more wire at the joint that's already there. However it's done, make sure it's solidly connected, and well insulated. If this circuit goes open, then your whole power block shuts down. Imagine that on a dark and rainy night.
 
TheDirty is right; back your camera up a bit. It's hard to tell exactly what's going on given a very blurry, partial schematic. Which bike is this being installed?

Generally, Red is + and Green - but without context, I could be mistaken. You can choose almost any switched power line to control the distribution block's Switched power relay because the current draw will be minimal. I think it would be best to mount the block near the fuse box and connect to a switched wire in that area. It would be protected from the environment just as well and it would make sense to route wiring that will be connected to the block towards that location. Easier to debug electrical bugs that way.

Solder all connections and use shrinkwrap tubing to insulate. You'll appreciate it later on. Do not use the wire taps as shown on the web page. They will definitely fail.

thanks for the reply guys ! really appreciate it all the help. i have scanned it (finally the scanner worked !). hopefully the new image will help. im doing it for my shadow.
 
1. Yes, Green is the line you want to tap.
2. It doesn't really matter if you tap into A, B or C. If B is the easiest to access, then use it. If you are adverse to soldering the connections, use Positap connectors for sure ( http://www.webbikeworld.com/r2/posi-tap/posi-tap.htm ).

There is little that can go wrong if you take your time and do the electrical connections properly. The relay connection is only going to draw milliamperes when activated so it will not load the tail light circuit.
 
Notice that the green is common to all 3 bulbs. This, plus the fact that this is a Honda, indicates that the green is ground. If you tap into that for power, you will blow the fuse. I ran into that problem back in 1984 with a new Magna that I was trying to put lights on without a wiring diagram. I learned the hard way that Honda uses green for ground. You should follow the wires all the way through the wing diagram to be shure.

hmmmm

rob said tap in green wire ...

peter said green is ground ....

i should tap the hot wire right ???

The green is ground. The green with yellow tracer is the brake light. You want to tap into the running and license plate light feed, and that is fed by the brown wire.

Not on a Honda. Look at the wiring schematic - the green wire leads into every light bulb, turn signals on each side of the bike, the license plate light, and the common ground for each filament in the dual-filament bulb that serves as both brake and running light.
