Brake light wiring.

Just installed a Coocase top box with built in light kit. Is it possible to access hot wire for brake/running light without
dismantling half the bike??

Yes, the wires are just accessible from under the seat through left side lamp access cover.

Of course if you purchase the perfect connector from DennisB its a whole lot easier. Check out this post: https://www.silverwing600.com/t992-the-perfect-connector-for-led-lights-hook-up?highlight=connector

Dom (or anyone who's done similar), I'd be interested to know the tidiest cable route from the box/rack to the bike's wiring. I can't see a clean way in without drilling through somewhere.

Here's where I threaded mine through:

Thanks Mike. I've yet to remove the rack, so wasn't aware of the rabbit hole.

It's a tight fit with the Admore bar cable but seemed to be okay - it's tight enough to prevent any movement and therefore chafing.

When i ran the wire for my top box brake light i did the same wire route without issues. I ran the wire under the rack (sandwiched between the upper steel and the plastic under cover) and drilled a hole in the UNDERSIDE of the rack (the plastic part) in the center about an inch in from the trailing edge of the rack. I didnt have the heart to drill a hole thru the steel rack. The wire is then exposed up around the the very back edge of the rack and then under the top box where it is connected with quick connects so the box can be easily removed. The wire isnt really noticable unless your looking for it. You can check it out in my album. To make the wiring connection easier on the bike end i removed the left rear side panel, the part with the key to open the seat. This makes the wiring sooooo much easier. I dont think i would be able to connect the wires thru the little access holes under the seat!! Removing the panel is a one minute job. I spliced the wires into the appropriate ones then soldered it for a permanent connection. It sounds a little confusing but is relatively easy.

I used the DennisB Perfect Connector; there are other pictures of my installation in my Album.

I just checked my album pics to see if there was a pic that the wire can be seen as i mentioned in the above post. There is one pic that if zoomed in you can see the wire looping from under the rack to the underside of top box. Just thought i'd let you know!

Good stuff people. Thanks.

Yep, me too same as MikeO, nicely discreet and no drilling or cutting needed. I just tapped into the brake light wire in the harness under the left side cover, ran the red (on my 37V Coocase box for the alarm and remote) along the route of the main battery cable and then through a fuse holder to the battery with a ring terminal on the battery screw. The ground wire was also tapped into the harness ground wire. Both taps were twisted, soldered and covered with a piece of shrink tube.
