December 31, 2009 - After the big dramatic day of pulling out the engine, I continued to work.
That great engine is worthless without the wiring to run it, so I spent several days pulling out what I needed. Yanking out a wiring harness without chopping it up requires fairly substantial disassembly of the car, including pulling the dash.
GM made some weird choices when it comes to connectors. Some are the excellent GM "Weatherpak" ones. But some of the parts that appear to be sourced from the outside use a wide variety of completely different connector designs. It's a bit ridiculous, making the wiring harness appear to have been designed by a half dozen teams that never actually talked to each other.
A number of connectors are locked in to place with a secondary pin. In the picture, the orange insert needs to be pulled out (which, in this case, involved a dental pick to depress the small and difficult to access tangs) before the blue section can be removed. Why? It certainly makes the car harder to assemble and to work on. Most of the other connectors have a more common clip that can be released easily. But for some reason, there's a guy at Chevy who's paranoid about how secure a connector has to be.
