2002 Wiring harness question

I reworked my 2002 harness. I went and got the mating connectors for the inline harness connectors in the harness already. I have it set up so that the whole engine harness is disconnectable and every connection is watertight. Also all power circuits are fused as designed by GM. It's worth spending the time to do this right so it doesn't become a problem in the future. If you need part numbers for the connectors let me know.

I also did this. I did no cutting to the orignal harness. I mated the GM connectors to a 1997 Camaro LT1 fuse/relay block. With this block came the harness for the e-fans and the connector for the cruise control so it just got better and better. I did splice into the orignal 2002 LS1 harness for speedo, tach and a couple of other things. Using the connectors worked out nice when I got a added the SLP cooling fan switch, it just pluged right in!

I finally had time to go out and look at my harness. There isn't much to clean up if any that I can see. Every wire goes to something except for the 4 connectors and a vacuum line right at the computer. There are also 2 connectors one white and one blue that go through the fire wall.

So here is what I have left:

1. Blue 10 pin connector to cab.

2. White 10 pin connector to cab.

3. 1 single connector with large purple wire to it.

4. Grey 10 pin connector by pcm - only 8 wires used.

5. Black 8 pin connector by pcm - only 5 wires used.

6. Black 10 pin connector by pcm - only 9 wires used.

7. 1 small vacuum line wich tee's into the back of the intake. Not sure what this went to.

8. 1 large red wire from battery to old fuse box.

I think Items 1 or 2 go to the Data port.
I glanced at a guys 2002 WS6 and looked like items 4, 5 and 6 above go to the fans and the fuse box on the drivers side fender. Has anyone used the T/A fuse/relay box or is it too much trouble?

If you have any input, please let me know.
Thanks

3 is for the starter, you won't need this one. 7 probally used for the AC controls, I think I hooked this one up to the vaccuum line going to a cansiter that goes to the AC controls to switch the inside vents. You can use the T/A fuse/relay box, but I think it has two boxes hooked together and a bunch of things you won't need.
