I have a 89 LX and I originally pulled my harness from the computer and tried to hook up a harness from a 90 and found that its not compatible. So I just pulled it out and put mine back in and I started the car and I have no dash lights , my factory tach and other gyuages aren't working, my high beam light is on when my lights are on low beam and if I put them on high beam than the light goes out. I hope I didnt fry the computer by hooking it back up with the battery still hooked up. The only thing I did differnt was grounded one ground that has an orange wire to the firewall instead of the motor. It is still grounded to metal though. Also with the key off if I turn on my headlights I can hear my fuel pump turn on. Can someone please help me?
