A/F gauge for 88 or 89 accords

[1988starter]

OK I know how to hook up my gauge red to + black to - and purple to an O2 sensor. BUT I was wondering if I should splice the purple into both of the O2 sensors that the 88 and 89's came with or just one and if one should I go primary or secondary.

Just one... and if the O2 sensor is being used don't count on both getting a good signal.
