The white plug in module just tells the dash if it is instslleed in a 4 / 6 cylinder car... never ever known of one go wrong.

Can't think of an obvious cure, but you need to check all the connections, did the service lights work OK? have the batteries leaked inside the cluster?

batteries leaked inside the cluster??
it happened after some weldin i done however the main battery was disconected.
service lights work ok, i jus cant think what it could be.

SI board batteries have been left without their charging current, and are susceptible to the present cold weather.
If you have the cluster out, take out the SI board and check the voltage of the two batteries.
Other possibilities are fuses 10, 12 and 21, all of which relate to the instrument cluster.
