Ive just replaced the cluster and replaced the sensor, So im tryin to find someone that knows about wiring that can maybe help me figure it out. I have a 96 Audi A4

Stupid question but do you have any wiering diagrams for the car? If so I can more than likely help you.

I have a book for the car that shows wiring diagrams but im not positive if its on there, honestly im not even sure what to look for, do you know of any sites that are good to find wiring diagrams?

Are you sure its the cluster?

its a wire goin to it have put 2 new clusters in it now and have already changed the sensor
