stock dash board issues or worse?
So i recently purchaced a1992 bronco eddie baurer ed. Has 171xxx miles. I just had it all timed looked at tuned up oil changed all that good stuff. Now i noticed that my lights on thw bottom left hand corner (like the left hamd blinker)dont work the cruise control doesnt work and when i open the driver side door the lights dont come on. Thays not it just yet. The oil pressure gauge is fine when i first start up and drive for about 15 20 mins than it starts fluctuating at idle in park or driving down the road and so will the volt meter will go up and down and the gas gauge goes up and down about am 1/8 of a tank as im driving. Now my main concern is the oil gauge. Now there is no knock ticks or lifter noises even when the gauge drops to nothing and when i say nothing i mean the gauge is maxed out low. No odd smells noises or drive ability. It has 20w50 oil in it and i just replaced the oil pressure sender unit which is a single wire. And tore my dash board apart hoping to fine a bad connector in it with no shorts that i believe so if im having all these problems electrically is the the wire harness f***ed up somewhere or am i just imagining things. Any help would b appricated
