94 Ram b350 speedometer failure

Not sure if this belongs here or not but here goes... My 94 ram b350 vans speedometer quit. I pulled the vss electrical connector and trans fluid came out(not good). So I replaced the vss and still no working speedometer. The fuse is good. I cannot find a wiring diagram online. Everything else on dash works. Vehicle is running ok. Key on off test gives me a 3 3 3 55. Which is odd because it should only be 2 digit codes. Unhooked battery- no change. Any suggestions??
