so i finally got my 89 hatchie running.....lmao. Now i got a cluster problem. It being a dx (no tach) was not going to suffice, so i have an 88-89 si cluster, my issue is this, all of the plugs from the dash harness i have mate....except one, that goes to the tail lights...rear turns etc....rear of the car in other words. I believe the harness came out of a 90-91 considering the plug being different, it also has a couple extra wires going to it. Would it be better to just get the new harness or rewire this one? $ is not the issue really.
