I just got my hands on a console gauge cluster.It looks like it is complete, with the wiring harness in tact. My question is this. Sense my car did not come equiped with this option is there a plug in my car allready from the factory that the cluster harness will plug right into? Also, where does the round plug on the cluster harness attach . It is for the fuel gauge. I'll have to buy a in dash tach to replace the existing fuel gauge. Someone did cut the wires which look like they power the whole cluster. One is a white wire and the other is yellow. Where do these go? I guess I forgot to mention this is on my 69 Camaro. Thanks for your help!
