probably pretty self explanatory. label all the connections just to be safe, removing the hood helps a lot. fan shroud, idk have fun!

 

[07Burb]

X2 on the labeling!!! Also take your time and don't rush it. When you get in a hurry stuff breaks

Pfft no need to label, everything only goes on place in one direction. and the way the wiring harness is bundled only one thing really fits close ...

Sunlit may or may not have copy/pasted

I always use the label route cuz it makes life a lot easier when it comes time to hook everything back up even if the item is obvious!

 

[SunlitComet]

true on both statements. If anything try to label which conduit went through which clamp through path around the engine.

You could also take a lot of pictures, that helps me when figuring where things came from!
