I have a 90 si and I think the dash and harness for cluster is from an hf. I just put this car together and tach don't work. I refrenced the plugs and wiring didn't match for an si. I do have the small blue plug in center and learned it was for a hf. what would be the best route to get everything functional?

Pics are wire locations for a 90/91

The 88/89 are different.

Link will help if you have a 88/89 cluster or harness in the mix.. http://crxcommunity.com/viewtopic.php?t=6184

I tried all 4 diagrams and E&F worked best but not 100* I am curious as to what the blue plug is for. (c711) my book says HF only. I have a socket for it in rear of cluster and also on harness. The car is a Si which shouldn't have one according to my book. WTF is the blue 5-wire plug for?
