2003 C320 instrument cluster pin-out
 

Hey guys.. newbee here.. I just picked up a low miles 03' C320 in fabulous shape.. The only thing i don't like about the car is the instrument cluster doesn't show engine temp constantly... Who cares what the temp is outside? I want to know what my engine temp is running at !!!!.. What I really would like to do is swap my 03' cluster for a 05' with the temp guage.. Anybody try this ? I don't care about all the BS info data.. I'm am industrial electronic tect by profession.. I work on Siemens, Fanuc, etc.. electronic gear everyday.. so I'm not too worried about making wiring harness changes.. So where can I get the 03' cluster pin-out and a 05' pin-out.. Thanks, for any info and help you can provide...
