Here is where I am at. Ran the harness under the dash, the BCM is in the kick panel and all the spare "future consideration" wires are in the plastic run under the sill plate, the neutral safety switch wires are lined up with the shifter, the ALDL and brake wires are in place. I do need to remove the stock cruise control box as it won't be needed.
I also laid out the fuse blocks and the PCM/ECM wiring; and if you can't tell I need to extend the wires for the cruise control and friends about 30" or so. Then I grabbed the cruise control module and gave it a trial fit. And finally since I was in such a good mood I decided to treat myself to running the throttle cable - I hooked a spring to the engine side and sat in the car making vroom vroom noises and rowing through the notional gears.
And that pile of wires is the aftermath of a month's worth of evenings and weekends.
