What can we say, brilliant value, just brilliant.
This version of the Autoswitch is designed to suit all BMW models from 1995 on.
The 5NB2 version is to be used as a SECOND controller for a second use. Activates a second relay without affecting the first one. This model takes 2 quick pulses BEFORE the 1.2-10.0 second release window of the normal 5NB.
It takes a negative (ground) pulse from your turn signal cancel button.
You just hold the button for more than 0.8 second to switch your auxiliary light relay on or off.
When you want to cancel a turn signal you do it normally, by a quick tap on the button, usually no more than half a second.
