Well, I'm happy to report only minor cuts and busted knuckles during the harness transfusion. I ended up using my dash as well as the harness. My 00 still had the pull out headlight switch. The 05 did not. I needed that as I am keeping my 00 steering wheel. The 05 donor tub did not come with one.
I also did keep the 05 HVAC system and ducting. The ducting is all 1 piece which I thought would eliminate the whistling that sometimes happens. Also the HVAC unit on the 05 donor is all inside while my on my 00, the fan actually mounts to the firewall. The 05 donor tub did not have the opening on the firewall, so I kind of had to keep the 05 HVAC unit. The plugs and vacuum lines all matched up so let's hope all the settings work.
Lastly, I kept the rear taillight section of the 05 harness. I had to splice that in as there is no plug at that point in the harness. I did so because my 00 harness at that point is crap. The rust and corrosion had eaten on the wiring back there pretty bad.
All in all, not too crazy. I just went methodically through each part and section...practically side by side.
Oh, I almost forgot...while both the dashes were out of each tub, I took the opportunity to EASILY switch the pedals over. My 00 is a stick and the donor 05 tub was an automatic . it was super easy to get to all the nuts to swap things over.
I'll have some pics later.
