There are few critical connectors I am missing thus far. I know where to find them, but Mouser and wiring information I do not have.

Fuel Injector Connectors
Fuse Box Connectors
Knock Sensor Connectors
PCM Connectors (Blue and Clear. I KNOW these are available, so if anyone can point me to a source I'll get this updated).

Maybe a couple others. I'll try and update this information as I find more stuff. Im mainly after under-the-hood stuff associated with the main harness (I think there is like three harnesses). So if you come across anything that is useful, particularly inexpensive parts sources for anything Im missing, PM me with the information and I'll update.

Hope this helps someone out. It looks to be relatively inexpensive to get the connectors. Maybe $50 - 60 for all of them in the main harness? Somewhere in there. Ive found sources for the appropriate TXL wiring too. Thats obviously going to cost a bit more but its worth it to go in there and wire in the harness the way I want it.

Here are the wire colors you'll encounter based on the diagrams so far:

SOLID COLOR / STRIPE

YELLOW
BLACK/WHITE
PINK
BLACK
DARK BLUE
GRAY
BROWN/WHITE
WHITE/BLACK
LIGHT BLUE/WHITE
LIGHT GREEN/BLACK
LIGHT GREEN/WHITE
LIGHT BLUE/BLACK
ORANGE/BLACK
LIGHT GREEN
TAN
PURPLE
TAN/WHITE
PURPLE/WHITE
RED
BROWN
GRAY/BLACK
DARK GREEN/WHITE
DARK GREEN
WHITE
YELLOW/BLACK
RED/BLACK
DARK BLUE/WHITE
LIGHT BLUE
ORANGE

Quite frankly, if you were careful in what you did and was meticulous in labeling everything, you could minimize those colors down to just a handfull

Red - 12v
Pink - Ignition 12v
Black - Grounds

Then just pick out a few other colors for anything that carries a signal, such as the MAF signal. I can almost guarantee you that you will have to resort to such a tactic if you want to do this work. Striped color TXL wire has proven very difficult to find.

However there are a ton of pink wires in the harness, tons of black and red. And Ive toyed with just pulling the grounds out of the harness and connecting them at the point of the sensor. For instance, the MAF has a ground wire. I dont believe it has to run through the harness, so why not connect it right there at the sensor location or in close proximity.

I think there are a lot of little ways to cut down on the number of wires in the harness. For instance you could run a common ground point to a couple different places in the engine bay and do the same for any +12v supply voltage.

Anyway, that is where Im at. Once I have the connectors I'll begin cutting mine in order to de-tangle the harness and find out what would be the best way to route everything.

Synth, if you want I can get you the Delphi part number and wiring information for those connectors from the GM SI manual. A lot like what you have above, but no Mouser info.

If you could please that would be much appreciated. Particularly the Knock sensor and fuel injector connector since I could not even find those in All Data. I think All Data had part numbers for the fuse block connectors, I just couldnt find a source for them anywhere to purchase. Same with the PCM connectors.

But please, anything you can send my way would be much appreciated.
