Heres the problem...I had a 88 tach in my 88 crx si correct ? Ok...i had to chagne it out..i got an 89 but it has a blue plug in the center..the tach goes crazy...gas doesnt work nor does temp gauge....engine light stays on...tach quits after awhile...very weird stuff happens. Whats the deal ? Im having a hard time finding another 88 si cluster
