cluster mayhem!!!!

So i'm losing my mind with my clusters.....

first i had an unknown cluster (with the dudmmy lights instead of oil,vot and temp gugages) in my truck nothing worked... Dash lights included

than i put an 78ish cluster in dash lights worked...and temp does the full rotation on start up but never shows the temp?

got an 85 cluster and all hell broke lose....right turn signal stayed on, when you turned on the left blinker they both blinked... the dash lights work but are very very dim. gas guage seems to work but when you turn the head/park lights the gas guage goes to empty?

i think thats all the wacky stuff that happening.

anyone have any ideas or am i going to have to re wire this beast?
