Quick question about dash harness
 

Hi guys, i just took out my dashboard on my 86 gxl because the previous owner had a half installed wireless ignition/alarm system in there (bare wire going nowhere, connecters hanging everywhere *shudder*)

Anyways, i'm starting to think that it would be easier to just install an non-screwed with dash harness in place of the old one. My question is can I use a harness from say an S4 vert, or even an S5? or are they different?

I would imagine the harness would have to match the peripherals that your car has in the dash. It would be best to just use a NA S4 non vert that has the same stuff.
