Speedometer help!!!
 

alright i have an 86 k5 and the speedometer wasnt working when i bought it so i bought a cable for it and the transfer case is np208 so i got the cable hooked up and and get the dash apart and what do you know the speedometer is electric... so yea it has a th350 trans so somebody along the lines did some swapping and i saw 2 plugs dangling on the drivers side and i think one of em is for the speedo and not sure what the other one is for... but what transfer case should be in this truck? i dont know how to upload pics otherwise i would show you what plugs are hanging there. Or does anyone know of an aftermarket speedo that would work and not cost an arm and a leg?
