I actually only cut one wire going to the locking pump. If you pull off the cover on the pump, you can clearly see the wire that has been cut, with each end now being connected to the keyless module. The other wires are for power and ground.

If I had to diagnose anything in an older car and came across a box like this, the first thing I'd logically do is disconnect power and ground. If it didn't start working (ie. those cut wires need to be reconnected), it's pretty easy to see a cut green wire and the solution would be to reconnect the ends.

I don't think it's any more complex than replacing a non-factory stereo with another one. Wiring harnesses are different, but as soon as you pull the radio it's pretty easy to figure out.
