hi guys. Im working on a 72 mercedes 250 (vin= 011)
I have no dash lights. Took a test light,i have a power input from the headlight switch to the cluster,but no cluster lights or dash lights.

HELP!!!!! im frazzled! already checked the fuses under the hood with a test light,all ok! DOes anybody have a good diagram that actually shows the cluster with pin numbers? thanks!
