I know I need the following 1. The OBC Unit with thin connection wiring 2. Selector Stalk Are there any other bits? Also, where does the OBC connect to ? Should there be a spare socket on the rear of the instrument cluster ?

You will need a harness to connect everything. I was wondering if there is anything behind the cluster to deal with too. I don't think there is. I can see what parts I have at home, to give you a more precise parts list. I don't have the OBC computer/clock , so I will not actually be completing this mod on Sunday.

Posts: 3,156 | I'm reasonably certain you connect to the ECU, and not the cluster. But, I don't have one and don't plan to, so I am not the authority on this... | | | 11-15-2006, 12:22 AM | #4 | Senior Member Join Date: Sep 2004 Location: Manassas, VA Posts: 4,129 | I think I have the BMW retrofit instructions, need to read through them again.

I now know what I'm letting myself in for which thankfully looks reasonably straight forward. Cormac | | | 11-18-2006, 04:27 PM | #8 | Member Join Date: Nov 2006 Location: Dublin, Ireland Posts: 47 | Sorry guys, One final (I hope) question. It says on the instructions that the "vehicle data must be programmed into the unit within 36 hrs" If I bought a second hand unit which came from a 316i, would this mean that this step would NOT be required ? Cormac | | | 11-18-2006, 04:35 PM | #9 | Senior Member Join Date: Sep 2004 Location: Manassas, VA Posts: 4,129 | I'm starting this update tomorrow, and I do not have the OBC computer. I wonder if I install all the wiring, and leave the cable that connects to the computer off, is the 36 hour time limit an issue.

It will be interesting to hear how well the BMW instructions match up to your actual experience Cormac | | | 11-19-2006, 11:10 AM | #12 | Senior Member Join Date: Nov 2004 Location: Bremerhaven, Germany Posts: 977 | Quote: Originally Posted by L84THSKY I'm starting this update tomorrow, and I do not have the OBC computer.
