97 gtx no gauges no beep

[dozer85]

Have matching skis so I’ve taken every single electric/computer part out and tested it on the good ski and they all work new dess switch solenoid new starter (works when jump solenoid) but other then the s/s switch and the gauges themselves I’ve swapped out every part and nothing else is wrong .. could the s/s switch being bad make the the whole dash dead?
