Well, I've dug through mine a few times, and I've only ever thought it was all very simple--compared to a lot of newer cars, for instance, most things are very simple screw-clip-unplug, etc.
And not that much wiring, either, but some oddities just due to the nature of the design--like the main radio controller being in the trunk and such.
Regardless, still good you're getting it fixed...just be a little more careful about what you cut or drill into next time (that applies for any car). These cars are still really, really simple in the scope of things, so that's usually good when it comes to taking apart & fixing or replacing. At least it has been for me.
