ok,
I have a 90 civic dx 4dr (it shows august 89 on door)
and am lookng into upgrading my gauge cluster to 1 with a tach.
I got 1 already from a 89 civic lx and the tach didnt work and it wasnt rounded like mine was.
Well i found two edm clusters with 155mph speedo and 9.5k redline tach
1 is from a 89 crx and has only two plugs on the back like my curent cluster but the other is from a 90 civic and has 3 plugsand a bunch of extra lights like "alb" and "gas", the 3rd is a small blue plug what is this plug for? will either of these work for me?
plz help me
