Attached are the wiring diagrams for the 81. Wiring issues are somewhat common on 'Vettes due to the way they were built in those days. The dome light on is likely a bad door switch. Unfortunately the online service info doesn't cover those years very well because GM was still using paper books for most of the work. If it were mine I would order a couple books for it. One the factory service manual for it. The other is the factory assembly manual for it. The first one has better wiring info and breakdowns for the individual systems, the second one shows things like how the dash goes in, or how the wiring would be run through the body. Very good to have both for them.
