Harness Identification Question - Blue Green? Hey All,
I've got a harness here I need help identifying.
It has blue and green PCM connectors and what appears to be a screw on fuse block connector. I've looked on
/lt1swap and it says 03+ trucks were blue green. I've compared my harness to their pinouts, but the colors don't exactly match up in some places.
What I want to know is, which vehicles used blue green? Also, is there a way to tell if this is a DBW or DBC harness?
I can take pictures of parts if anyone can help identify it.
The only identifying numbers on it are 6662 or 206662. The main tag, which I think had the real part number, is faded out. I was told it was an 01 LS Auto harness, but does not look to be so. Did anything in 01 have blue green connectors?
TIA!

When I done my harness using LT1swap's site there were a few wires that did not match the pin outs he has, I asked him if that was normal and he said yes. I just used my multi meter sent to audible continuity and traced them out and labled accordingly. It was an 05 DBW harness ,I have also done a 2000 DBC harness as well and there are just a couple plugs that are on the DBW that the DBC dont have. If you can post some pics maybe I can help identify your harness for you.

Looks identical to my 05 harness. It is a DBW harness. And that positive battery harness will be done away with if you mod the harness yourself. Also did you get the battery ground wire setup with it? If you did is there a black box attached to the wire with a bracket?

Don't think I got the battery ground setup. No sign of a black box/brack. The pic above is all that was in the box.
I think you're right. The closest pinouts on lt1swap was from 05.
I won't be using it as it was the wrong harness for my bro's car. I've since got the correct one. I'll be throwing it back on the classifieds.
Thanks man for your help.

I just googled the part number on mine #15192310 and it came up with 03. I tried the numbers you have listed and do not think that is the part number. I need to look at mine and see what wires are what, but yours looks like my harness.

Lol, dammit. The plot thickens....
I figure all 03-07 harnesses would look similar. It's just narrowing down specific pins that's the problem. Grrrrrrrrr.

When i done my harness I think i had 2 pins ( 1 on the blue connector 1 on the green)that the intructions told me to add pins for that were already pinned. They were the pins for electric fan #1 and #2 functions.When i asked Brendan from LT1 swap about it he said that in 05 and up they were already pinned. Also on the Big Black plug (C2) some of those wires were not where they said they should have been either, thats when i got out the multi meter and traced them out so it would make sense to me.

I think mine is black also but will check tomorrow when I go to the garage. Is there a sticker on back of your pcm connectors (blue and green)? Mine had a small sticker there that had part number for pcm harness on it.

Only the blue one has a sticker and that was 20662 with a barcode. The tag that's like an inch down from the connectors is faded out.
I'm fairly certain it's an 05+ auto truck harness. I did a pinout comparison of the blue connector vs the 03-07 lt1swap website and it is pretty much the same from the pinouts I compared to.
Two wires on the C100 don't match up to this 05 pinout. Haven't looked over the C2 in depth as that's confusing.

The C2 confused me to till I got the meter out and traced them out . the wire colors for all the other conections I.E. fuel pump ,vss,engine speed(tach) etc. were all right with the site just some were in different spots than the site says. had some pink wires as well. I believe the 02 sensors and tac module, maybe another.But like i said all wires corresponded to there rightful connectors and colors. i believe my 152 was grey as well on the 05 harness the 2000 harness i cant remember.
