on my 1980 olds cutlass calis i finally found my data plate now i just need it interpreted. it was at the base of the windsheld on the drivers side.now i just need to fix the electrical,headlights,tail lights,i think that is the light switch,the wiper,it worked for about 10 sec then stopped,the blower fan,if i hook 12v to it directly it works i am thinking switch,and all my gauges except the tach it comes on when i turn the key on but it doesn't go to zero just twiches around 3000. but the car runs and the alternator works. oh well one thing at a time. oh yea the radio doesn't work and neither does the electric windows and the electric seats
