Sidecar Wiring HELP!!

[guitarzan]

Hello,
I have a 1994 Goldwing SE 1500 and I'm going to try and mount a sidecar to the bike but I'm looking for a place to splice the sidecar tail light, brake light but I don't know how to read the schematic. Is there a place that is accessible under the seat? I would sure appreciate any help.

Respectfully

I'll see if I can be of any help here. I just installed a trike kit on my bike and had to splice into the wiring also and on mine I chose to go to the wires in the rear corners where the wrap around trim goes at the rear of the saddle bags. It's pretty easy to get to and you can get all of the connections you need from just the right side except the left turn signal. I like to use this type of tap as it is easy and clean:

Not to say you need this kit but this is what I use.
White wire = tail light
Yellow wire = left turn
Green wire = right turn
Brown wire = brake lights

Oh and you can also go to the bulbs in the trunk if you want.

I gave you the normal trailer wiring colors but didn't give you the Honda wiring colors which are:
Green is ground
Brown is the taillights
Orange is the left turn signal
Light blue is the right
Green/yellow is the brakes
Hope it all goes smoothly for you.

Just saw your post... hope you have not cut any wires yet

The way to go is to use a trailer wiring harness. Cycle max has 2 options for you:
GL1500 Trailer Wiring Harness (B2-448)
This is a trailer wiring harness. It is made by Show Chrome and is designed to plug right into the factory wiring harness on all years of Goldwing GL1500's from 1988-2000. This is a 5 wire harness. If you are using a trailer with a 4 wire system, you will also need to purchase a 5 to 4 converter. The trailer end of this harness has five single wires so, you will need to get a plug for this end of the harness to match the plug on your trailer. 2-448
$16.95

GL1500 ISO Trailer Wiring Harness (45-8945)
This is an isolated trailer wiring harness. It is designed to isolate the wiring between the bike and the trailer to prevent electrical feedback into the bike. It also reduces the chance of overloading the bikes taillight circuits. This is a 5 wire harness. If you are using a trailer with a 4 wire system, you will also need to purchase a 5 to 4 converter. This 5 wire harness gets the power for the trailer lights directly from the bike battery. It has four relays that are activated by the bikes factory wiring harness. This plug and play harness comes with complete instructions and will fit on all Goldwing GL1500's from 1988-2000.
$26.38

When I first hook up my CSC III to my 1990 GW, I used the B2-448 harness. I recently replace it to the 45-8945 harness to reduce the load on the OEM wiring. Not sure I really needed to do that but it makes me feel better. Make for a clean install without messing up your bike main harness...
Let me know if you need further help!
What sidecar are you mounting?
Cheers.
