Speedometer help needed!
 

After swapping out a different speedometer for a friend to prove it worked[it did], put mine back in and must have changed the wires. I searched the BBS and found photo's but not for an 83sc. I tried the set up for an earlier SC to no avail. In that configuration the speedo goes straight to 160 as soon as the key is turned. Any input is great, if anyone with an 83 would like to write down or photograph the wires it would be greatly welcomed. TIA
