If you read his earlier posts, the terminals were a special order item from the dealer (not stocked items). It would be helpful to have part numbers/prices for all the necessary parts on the How-to page for reference.

 

Actually he didn't get the terminals from the dealer.

The terminals are listed as being Packard Electric part #1204 0511 (they are a pain to find).

Gotta say it........

If we can't get the connectors, this is a useless how-to.

How do we contact them. I did a internet search and couldn't find them.

 

I've found references to the part number (12040511) on several sites, but no place to actually order it.

Some sites show it as a Delphi terminal (Packard Electric is part of Delphi)

EDIT: gmpartscheap.com has them for 51 cents each (plus $9.95 shipping ).

 

As long as I can get it somewhere I'll be happy!

 

https://www.partszoneonline.com also has the terminal @.45. So one ould just order all the parts from them for just one shipping fee...

And no, P&G Chevy doesn't pay me....

 

Sweet another "add-on" for my HHR.

 

That was a good find on gmpartszoneonline. My local dealer and gmpartsdirect showed that as a bad part#, so I assumed that other online GM parts sources wouldn't have it either.

The next how-to will be converting the outside mirrors to heated mirrors. I have all the parts here (heater elements and replacement glass pieces). It will be wired to operate whenever the rear defroster is on (like my other GM vehicles). Since winter is over (hopefully) I won't need heated mirrors until next winter, so the priority is low on my list right now. Some time over the summer I will do the conversion and will post a similar how-to for that.

OOps! forgot to answer crazybob's question. No, the car doesn't think that the door is open when I turn on the dome light. I specifically picked the BCM connection that wouldn't do that. The normal way for the dome light to come on is when the door switches indicate a door is open. The door switches are inputs to the BCM, which then grounds terminal A10 on the BCM to turn on the dome lights. Had I wired the dimmer switch to a door switch input on the BCM, then there would be a "door open" indication on the DIC. The way I wired the dimmers switch, it manually grounds the dome lights to turn them on. The BCM actually never knows that you have turned them on manually.

Also, the + power circuit for the dome lights is controlled by the BCM, so even if you turn them on manually with the dimmer switch, the battery-saving feature that turns off the interior lights 15min after turning off the ignition should still work.
