I purchased the online manual for my 1988 suburban, only to find out the main thing I needed was not there
There are only "general" wiring diagrams but nothing specific to the trucks themselves. I've puchased several paperback versions for various makes and models all have had wiring diagrams.
This truck is new to me and there are a few wires just sitting there unpluged, I know not all get used mpst times as harmess' are made to accommodate all options. I just want to make sure there is nothing important undone, as I have found a few mechanical fixes that weren't up to par.

Thank you
