The purpose of Smart LEDs has been discussed on an earlier separate thread:

One application is to add additional IR car strobe IDs. For example IDs 7-10 to expand the SSD system. Another example is to provide an alternative method for oXigen lap counting based on an extension of the SSD six car method.

I with a group of amazing and supportive friends are exploring both of these options and others too ;)

In this post I will focus on how to wire a Smart LED onto each of the three recent/present versions of oXigen wireless decoder.

In each case the Smart LED requires connection to four points on the decoder:

RED: +3.3 Volts
YELLOW: LED+ (or LED Anode)
WHITE: LED- (or LED Cathode)
BLACK: Zero Volts

Equipped with a fine tipped soldering iron the correct wiring points are shown below for each of the recent/present oXigen decoders. As you will see, the external LED attachment points are used in each case plus two further connect points for power.
