Need help with wiring accessories
Posted: Sun 23 Aug, 2026 6:55 pm
Hello everyone,
I installed a camera system and automatic chain oiler about a year ago and had no problems until recently.
First I was getting ABS alarms and my speed display was going up and down for a couple of seconds. The fault appeared very sporadically until last week when also light control and other alarms popped up. I tried two different batteries.
I disconnected the camera system and oiler and had no alarm today. So, it seems that one or both of them interfere with the CAN bus system somehow.
Both have three connectors. +12V, 0V and switched positive. I connected +12V and 0V directly to the battery (both systems have their own fuse) and connected the switched positive to the license plate light.
Not sure why I get problems after over a year of using these but it seems I have to connect them in a different way.
Can anyone help me and explain how to wire these correctly?
