Where to find ignition coil harness for 2005 TB 6 cyl

[Charles Austin Miller]

Need help finding an ignition coil harness for my 2005 Trailblazer LS EXT 6cyl 4.2L 4WD. I've searched the retail auto-parts outlets, Amazon and eBay, and nobody seems to carry the 6-connector harness for my vehicle. Nobody. Not even GMPartsGiant. Any ideas?

Maybe give Rock Auto a look at:

Harness might be one piece right from the PCM plugs (they are on a 2007). Rockauto has repair pigtails to fix the harness or bring a pair of side cutters to a pick'n'pull.

Might have to pull one from a junker. May still be available from the dealer at $$$.

The online microfiches, I found, don't list all parts. Go to a dealer and get the part number from them. Then plunk that number in online retailers.

Thanks, everyone. I have a couple of ignition coil connectors that appear to be melted, so I figured I'd just replace the whole harness. But, if it's hardwired right into the PCM, I might have to just splice in a couple of new pigtail connectors. And THOSE things range from $45 to $55 each, brand new. Might have to hit the scrapyard.
