The radio works great, am is the best!!!! When I replaced the circuit map and voltage regulator, I did not notice any damage to either, they just looked as old as me. I went ahead and used a test light on the cluster plug. If you number the connections 1 thru 7 on the left (#2 is empty), and 8-14 on the right the results are: with the motor running and the lights on: #6,8,9,10,14 would light up. Unfortunately I do not know what each of these correspond to. When I first bought the car 12 years ago, I believe all the gauges worked. I must admit that she has been setting untouched for about 6 years. Also, I have now discovered that my horn doesn't work either. Summary is as follows: absolutely none of the dash gauges or lights in the guages work; except the one telling me to fasten my seat belt, and now the horn has taken a crap. Any help would be super awesome
