Electrical Issues!

Just purchased an 89 HB 5 speed manual with 4x4. It has a crazy electrical issue where not much works (Gauges, Lights, fuel pump, horn) until I put the vehicle into gear and actually move it. The dummy lights, radio, headlight beeper and windshield wipers do work while the ignition is in the on position. I don't know much about electrical systems and have googled this to every corner of the universe with little luck. If someone could point me in the right direction it would be helpful, thank you!

Inspect all your connections and clean them if you can..these years had horrible plug/and connector protection like most cars in this era....I coated all my connector with Dow Corning 4 back in 88-89 when bought my 86.5 Used....Most of my engine connector weatherproofing boots are long gone so cleaning them with a small jewelers file maybe necessary to remove any corrosion....Once you get it cleaned I personal would clean them with an electrical cleaner add some dielectric grease to the terminals and fill the rear off the plugs with RTV....
