So as expected. I wired up the harness with relay and switch, 2 light and plugged it into the socket previously used by GPS connector (3 pin connector, 1+ / 1- and a data)
Lights turn on, stay on for a sec or two, then Canbus kicks in and shuts off the power to the socket.
So using a proper relay and fuse before connecting to the socket still asks for too much juice from the system, making canbus annoyed..
I want to run these lights using the existing wiring and making the lights turn off when the ignition turns off. Without a canbus system its very straightforward yet I'm stuck with this. I saw those other options of using a fancy fuse box yet this will set me back 200+ euro and I'm not too keen on this.
Now I did see a h7 canbus LED decoder. This you can use on LED headlights so that the computer doesn't throw codes and accepts it. So I was thinking, what if I do the following:
2x lights wired to the relay with each running through a canbus decoder before entering the relay.
OR,
Everything connected to the relay and between the relay +/- and the GPS connector +/- I place this decoder.
OR,
I could even splice from the existing headlights, making the sidelight LED's only turn on when the main bulbs turn on.. (if the canbus allows it)
What do you guys think? Also, I checked wiring and next to the GPS connector there's another connector with a cap on it. Perhaps a connector that allows more current? Or perhaps even 1 light per connector

My last option is to connect straight to the battery but then I lose the advantage of the ignition on/off aspect..
