as title says i have an 87 na 5 speed. bought it with a world of problems which i have fixed most. the only one i cant seem to figure out is the dang speedo. the speed sensor works perfect via the specs from the fsm. swapped out clusters with a known good working one. still same issue. the right turn signal indicator and speedometer dont work. any help or suggestions would be wonderful! thank you in advanced!

There was a plug from the dash harness above the ecu that was kind of cocked sideways so half of it had contact and other did not. Had i not started to swap the dash harness i probably wouldn't have noticed. Lol
