Does anyone know what the 3 unused button positions in the 87-90 pulsar nx xe/se on the left and right sides of the instrument cluster are for? I want to use them for accessories but i want to find the working button parts to swap into them. oh and the fourth light in the dash cluster, to the left of the fasten seatbelt light. I saw it when I was swapping my gauages for a working set a few weeks ago and put in new bulbs throughout. Has anyone seen the center dash gauges that the exa seems to have anywhere here in the US?
