These are great! Perhaps one of these will help me convert my idiot light setup to an all-gauges one. If one of this type is not here perhaps you have one...?

These provide the information about pin locations and the termination that are factory so it should be helpful.

Did you look in the The Squarebody Reference Library category? There are some GM Year Specific manuals in there. Just to have + them real big to see them but they work. If there isn't one for 83, look for 81 or 82 will be closer to your truck. In 84 GM went to the Multifunction switch on the column, so that one will be a bit different than yours.

Can someone tell me the bulb sizes for the tails? I think I know what the taillight bulb is but what is the reverse light? I didn't see that info in the above diagrams.

Yup, Elebum Fitty Sebum and Elebum Fitty Six will be most common bulbs on our Squares, and most USA made vehicles for the 70's and 80's for that matter.
