I am embarking on the OnStar telematics to Oem
bluetooth switch, and was wondering if anyone has any hints on how to remove the pins from the 42 pin connector.

People have mentioned using safety pin and jewlers screwdrivers....Stupid question where do you stick these implements?

Thanks

Remove the lock on the side where the wires go intot he plug (it slides of the connector away from the wires), then pull the insert out with the wires. After doing so you can see the actual pins and the little tab that you have to press down with a saml screwdriver.

This is a different plug but it works the same waht with the 42 pin OnStar connector.

insert out of the connector housing, but between the light in the trunk and my old eyes,I could not see where the tab I have to depress is.

One illustration of a pin removal tool showed it being inserted into the slot where the pin from the Bluetooth module would sit (the actual "socket"of the wire that is being switched) but I could not see any visible tabs.

Could you please confirm the tabs you are referring to are the second row up from the bottom on the side view of the connector that you posted the picture of

Thanks

on top you see the tab you have to push down and then pull the wire.

And this is the BT connector, next to the numbers you see where to insert the little screwdriver to push down the tab.

what I needed to know, before I started blindly poking away.

I originally contacted nsxjr for the kit but he doesnt ship to Canada,so I am doing it from what i can gather from various web pages.

As you can tell I am not electrically adept (or even remotely capable) but with this type of help it should be smooth sailing from here.

1) use an exacto knife to [carefully] remove some of the fabric tape leading to the 42 pin connector to expose about 6" of wiring. This will give you lots of freedom when you start relocating pins and eventually put less stress on the pins/wires between the 42 and 54 pin connectors

2) jewlers screwdriver is easiest for removing these pins but make sure you rebend the small tab if it becomes completely depressed. This will ensure a tight fit.

3) I use a small pair of needlenose pliers to help in removing the pins/wires by gently pulling on the wire when the pin/tab is depressed. This can be done with one person and one pair of hands but sometimes it can be easiest with a 2nd person.

4) mounting the OEM BT module:
In the C5, you need bent metal strap to mount the BT module in place of the onstar module. I also use foam tape (found in hardware store to cover pipes etc) to reduce any potential metal-on-metal vibrations/noise.

Lastly, take your time and triple check the pin locations during the process so you don't make a mistake.

Good luck!

and probably only install.

It went very well, I fabbed a bracket from steel strapping (horrible overkill).The telematics module lives under the rear hatshelf in the D2 so access is great.

Pin removal was easy once AudiA4B6US pointed out what I needed to do.

Once I got it fired up and recoded according to the instructions on NSXJR's site nothing worked, just a bunch of fault codes. I called it an evening.
The next day I disassembeled the connector, rechecked the wires (all intact), AND CLEARED THE FAULT CODES.

Everything worked great, being a Vag noob I did'nt realize that clearing the codes was necessary for the new codes to function properly. Or maybe it isnt and I just fixed a bunch of loose connections!

All I can say is this mod is fantastic automaticaly imports my phone book, all controls at my fingertips with the MFSW, voice activation if you want it

OEM is the best.

congrats!! Not so hard, isn't it?

I have done alot of mechanical work on my UrS4, my only foray into electrical work was hid headlight installation which hardly qualifies.

Once I had clear (K.I.S.S) instructions it was dead simple. Thank you for the earlier email.

I still dont know if it was necessary to clear the fault codes with the Vag Com to get the module to work after recoding or wether I repaired loose pins in the connector, when I rechecked it.

Great mod and a great resource
