Just a observation might be helpful to others, My trip computer never worked in my acclaim. I figured I messed up with the bulkheads pins. but no.
Recently I've installed a 91 daytona sbec replacing the shadow sbec i had. the traveller is now working just as it should. I figure the shadow computer is missing some hardware/programming for the trip computer.
heres a video of the unknown functions or perhaps just information screens.
