@Dean: I don't know of anyone else who has all the parts to fix it back to original... you have several wiring harnesses that you can fix it with. And you have the knowledge. But, do you have the time for it?
Someone to gut the stupid wiring issues, and fix it (you'd probably have to pull both wiring harnesses out, and just swap them with the ones you have), and other parts (steering column or holes in the dash) that were altered to take these mods... and then pull off all those mods (the car alarm, the remote starter, the delay wipers he's had added, or anything else that's been done...)
Then someone to fix the patches on the frame and body (Even Char would laugh at the poor welds on that car), and then you'd have a good SX/4.
That car has been poorly fixed, and altered in the most 'dumb' ways, that even I was surprised. The good thing about that car is it's drivetrain has been maintained, and there's alot of newer parts on it. So it's a good base, but there's alot of work to be done on it.
