SMG Retrofit

First things first. I am not responsible for any harm that you may inflict on either yourself or your car as a result of doing this modification. As with any modification of this nature, all risks are your own and any warranty concerns you may have are between you & your dealer.

To address the issue of the kit sold by Vincent Wong for $400. This modification was done using OEM parts, and OEM technology, so I am in no way stealing his or anyone elseís technology, etc. I am using parts from another BMW model, and using them in my own car. The only additional parts being some wire, wire taps, electrical tape, and a plug to make the wiring easier. Basically I tapped 2 wires; thatís it.
Anyone who has done even the most basic wiring can accomplish this task, and to the mods/admins, I am a fellow mod on a few forums. Please read the actual instructions to see what is involved in doing this install. In all my years (since 97), I have never heard of someone trying to charge for modifying OEM parts. This is the kind of thing is what all these internet boards were made for. If everyone charged instead of spreading info freely like is so routinely done, Id hate to know what these boards would be like. Especially in this case with a $325+ premium for tapping 2 wires. If the customer service and warranty (for what wire taps?) is worth it to you, by all means, buy his kit. It just wasnít for me.

This install was performed on a 2003 540i. The basics should be the same for other models, but I really wont be able to help if you have any specific questions about removing trim pieces, wire colors, etc. in another model, or year car. If you need help like that, maybe the retail paddle shift kit is something you should consider.

TOOLS & PARTS NEEDED

-Various Flathead & Phillips screwdrivers both large, small, long & stubby.
-Torx bits
-Ratchet Set
-2 pin female end plug. (This can be found at computer hardware stores, and is used for the LED lights that indicate/show your desktop is powered up/running.)
-24 gauge, or similar size wire
-circuit tester
-compatible wire taps
-electrical tape
-wire cutters
-pliers

-SMG steering wheel; Part # 32 34 2 282 222
-SMG steering column switch; Part #61 31 8 379 091
both purchased from Pacific for $562 plus shipping

The Basics

The SMG steering wheel has an extra 2 prong plug on it other wheels donít.


Old Wheel


SMG Wheel with extra two prong plug for the paddles

This plugs into the 2 prong jack on the front of the SMG steering wheel switch that is not present on other model cars.

Stock switch front


SMG switch front with additional 2 prong jack

The back of the switch also has another 2 prong jack on it that your old switch didnít.

Back stock switch


Back SMG switch

You need to run wires from there (using the 2 prong plug I mentioned above) to the shifter area where you will tap into the 2 wires that control the up/down shifts in tiptronic mode; Thatís it.

Two prong computer LED wire


OEM tiptronic wires/plug


Tapped


running wires

same


All Done!!

A step by step will be posted once i upload all the pics, but it is definitely going to take me a little bit to organize, and post up a complete how to including the pics; Good Luck

Something's not right with this - why aren't you charging $400 for this information? This board has been conditioned to believe that a 99 cent wire connector is worth $400 because of "the innovative, often brilliant, unrelenting pursuit of humanity's essence in the tireless effort to enrich our unfulfilled automotive desires." Mr. Original Shifty Paddler and his minions will demand an apology from you. On the internet no less

FYI, the phone buttons are connected to the IBus system so they do not run on separate wires through the column.

I am going to attempt to do this. I am assuming you tapped into the two center wires that are purple and blue. I have a few questions.

- Which colored wire is for "-" and which wire for "+". When using the 2 pin plug from a computer store, what color (red and white) goes to the steptronic wires (purple and blue).

-Where did you purchase the smg wheel and steering column switch and how much?

-Any advice you could give me before I attemot this.

Thanks,

Mike

i did this about a year ago on my 330i. it's by far my favorite mod of all time with all of my cars that i've owned through the years. the only problem was the price i paid to get it done.

smg wheel = $1100
sport airbag = $750

i didn't have the sport wheel in my car so i had to suck it up and buy a new airbag. my install was identical to the one posted above. 1 year and running without a hitch!!!

oh yeah, my car is an automatic for those who care to know

i believe that white was hot (+). to be honest with you i screwed it up the first time and found myself downshifting when i hit the + paddle. no biggie, just switched it and voila, no probs now. by the way, did anyone know that prior to 2002 sport shifters shifted up when pressed up on the stick instead of down... that's why i had the issue.

No offense, this looks like a sick mod for those with automatic transmissions, but an SMG M3 wheel should not cost more than $500 new. Someone took you to the bank.

Great mod tho

I am attempting this on my 2001 330i but with using the M3 Sport Mode Button to get it to shift into SD mode from D mode when the button is pressed without having to physically shift the shifter to the left.

Here is my pre-DIY video:


Also Subzeroe46 accomplished this with the paddles taking the place of a Sport Mode button. Here is his DIY-results video:
