1987 wiring help

Im used to working on the WWW (Weird and wonderful wiring) mainly on old bikes but the Vette has confused me.
Ive only had the car a couple of weeks and getting ready for the MOT.
Initially, the side lights and marker lights were working, the LH headlamp was loose, I repaired the bezel, then the RH hi beam went. After various rusty problems, the bezels and headlamp bulbs now work.. BUT, the side/park lights and side marker lights have stopped.

Secondly, the door mirrors do not move.
Thirdly, the radio does not work and the tools Ive got will not remove (Pioneer) (my problem) (thinking radio has a fuse)
Fourth the inside vanity mirrors dont light.
Fifth the screen washers dont work.

Ive checked the fuses as in the owners handbook, apart from the sidelights working that now dont, the rest have not worked since I got the car.
I know 1970's Harleys used resetable fuses but looking at Haynes I cant see a common feed to solve all.
cant see a feed for the vanity mirrors or door mirrors.

any thing I should look for first before I start pulling wires about? thanks

The side lights, do you mean the front fog lights or the lights just in front of the wheels ?
If both mirrors don't adjust I would look at the rocker switch that selects between sides as if this fails they both stop working.
Check the fusable links, on the jump start post behind the battery, this is the main power distribution point. It gets wet due to the hood catch drain hole being right above it. Clean and test all the wiring here first, as a bad connection here can cause lots of electrical issues.

thanks for the replies,
the side lights are the small bulbs in the headlights, the H4 bulbs are main and dip.
the marker lights being the ones on the sides by the wheels.
knowing American bikes, I thought there may be a fuseable link somewhere, it was just getting around to finding it.

it was just strange they all worked before I had to play with the bezels that hold the headlights in.

presumably the original washer pump is on the bottom or side of the reservoir? the car has a remote after market one fitted so thats the next thing for the mot.

The small bulbs in the headlights are not standard so someone has added them and there will be no wiring diagram to help.
