Hello guys and girls

I'm planning to do the whole power options thing in the doors of my 94Z and I have all the parts lined up exept for the wire harness.
Now here is my question. Since I alredy done the power trunk release (belive it or not it came from the factory without it) and the only things I needed where the release button and the actual mechanism - the whole thing was pre-wired. Now for the windows, locks and mirrors - is it the same case. Did the people in the factory ran all the harnesses through the doors and haven't installed the hardware or do I have to get the harness and run it through myself??

Please let me know on any info you got. It would real save me a lot of time and money
thanks in advance
Alex
