8 track player won't work?

[motornut]

I picked up one last year
put it in the 79
the brown orange plug on the back had to change the plastic plug to use one i had
in order to dim it needs to know when the lights are on so
brown i put to the markers/running light (dims with the dash lights)
orange to the lighter
the rest are the same
mine dosn't seen to have a balance tho,other wise it's great
