Working On OBC Hack, Need Help

[UNC Nick]

Hello all. I'm working on the OBC hack to use the stalk. I've already got the 4-stalk assembly installed, but was missing parts for the wiring harness so it could not be completed at that time. So, I ordered the connector that I needed to finish building the wiring harness and it came in the mail yesterday. I'm having a few things done to the car on Wednesday of this week so I wanted to have the harness built so that they could plug in the connector at that time. I ordered part # 999-650-056-40 from a dealer, but unbeknownst to me, I was shipped the "replacement part" for the part # that I ordered- replacement part # 999-650-513-40. I confirmed with the local dealer that this is the correct replacement part. Problem is, I can't figure out how in the world this part will work. The needed part is an electrical connector. The part that they shipped looks to be half of a connector. Does anyone have any idea of what I need to do or what an alternative is? Evidently, the original part is not available at all anymore. I really want the OBC installed and working with the stalk.

Thanks in advance! Nick

I think BMW makes an equivalent part - or at least used to. See http://www.renntech.org/forums/index.php?s...st=0entry6089 Sounds like the BMW part number is (was) 61-13-6-909-058. You might want to take the stalk with you to a BMW dealer to make sure the connector is the right one. Good luck

I too got this part when ordering bits for the OBC hack. However, I also got a packet marked 999.650.057.40 which is now a one piece part that fits into the OBC stalk wire. I'd try your dealer again... Or try an OPC.

I think it was Paul or someone else from the UK who reported a year or so ago that Porsche changed the part number and the style of the connector, but this had not yet happened in the US.

We use to order the connector 999 650 056 40 and the cover for the connector 999 650 056 56 that is shown on the right. It was black and there were 2 parts. I use to buy the identical parts from BMW.

The last few times I was at BMW BMW had changed the part. It was now blue and the cover was attached to the connector, so there was only one part to buy. That is the one on the right, but I have removed the cover so that it is in 2 pieces. I think Porsche has also switched to this style connector except the color is black.

The blue style connector works fine. In the second picture I have used it to make a harness.

Thanks Tool Pants! That helps a lot. Guess I just need to order the part from BMW. Is that the same part number referenced above?
