Hello peeps,
I'm not a mechanic, so I found this a bit unnerving to do on my own. But I took my time and I wanted to post my own write up because BMS's website and install guide does not match with our specific N20. The pictures in the BMS install guide shows a different setup than I had. So hopefully, these pictures will assist in future installs for us N20 Z4 guys/gals.
So here's where to get the original install guide.

From these pictures, one of the plugs was not where it was pictured. Note, I have an Electronic Wastegate (whatever that is, so plug 4 doesn't apply).

So here are the actual plugs that correspond to the BMS install guide for the Z4 N20 28i.

Finally, We don't have a Driver Side Cover on our Z4. So this picture doesn't apply:

So due to the lack of this cover, the JB unit is exposed to the elements, from the underside of the car. So I wrapped it in heavy vinyl, and zip tied it to the brace bar as pictured.

Notice that since this is Stage 1 only, there is no need to splice wires, connect to a battery or ground. Just 3 plugs, no tools.
I hope this write up will help others realize how easy this install really is.
Cheers,
APDspider
