I have an 86 gt and i swapped out all my harnesses for 87+, and when i went to hook up the instrument cluster stuff will light up but they wrong lights and some stuff even shorts out. for ex: when i put the right turn signal on, it lights up an illum. light behind the tach and flashes. and when i put my temporary brights on my pulling back on the wiper/washer handle, my left turn signal, right turn signal and bright lights all come on. I checked the wiring and the plugs that go to the instrument panel and the wiring is correct but when i look at the back of the cluster the wiring goes to the wrong lights. Im thinking maybe somewhere from 87-93 they switched the cluster or at least the wiring on the back. I have the mass air harness from the a 90's 5 liter and the dash harness from an 87 4 banger. everything works but my cluster wont. I know its a long post but if anyone can give me some info on the subject I would be very very appreciative
thanks
