Need help to get my brake lights and reverse light working

[Mo Power]

My turn signals work and I tryed my headlights and the left side is the only side in the rear that light up completly so something is screwy. If someone has a wiring diagrams for a 1972 B body that would be great or what color wire runs my brake lights in back. Cause I don't feel like getting pulled over in my Runner just after getting it back on the road  . Also what type of bulbs are used to light up the gauges because the bottom half is the only part that lights up on my dash.

brakes source runs through same turning wires... green and brown at the same time. this two wires are being feeded from turning switch. When you press brakes, a white wire coming from pedal switch feeds this two wires throught tunrning switch at the same time when you have switch off to any side.

Reverse light... fuse box ( on acc side a white wire ) feeds the NSS switch ( black wire ) on outer pin and when put REVERSE, NSS turns on the reverse lightning throught the other outer NSS pin ( black traced wire ). Then enters to the cab ( white traced wire ) and becomes on a violet wire on rear harness ( from kick panel "waffle" plug )

bulbs for all the rallye cluster lighning is 57
