Where do I hook up the brown brake (switched power) wire to in the car. Is there a wire under the dash that I hook it up to ? It's for resetting the 1st gear lock out after a run. Anyone ?

i used one of the accessory ports in the fuse panel.

It has to activate when you step on the brake. It reactivates the 1st gear lock out feature. Maybe it is up under the dash by the brake pedalv

also besides the 10 pin on a 2002 Z/28 where can I get the tach signal from ?

Well I went w the the 10 pin, set the BMN WS for 4 cyclinder and nothing. The set up led for power lights up thats it. I didn't hook up the brown brake wire. I wonder if that will cause it not to read ? I spliced directly into the 10 pin wire the old fasioned way, it's wire on wire so I know there is a connection.

I just went thru my install this past weekend. The brown wire needs to go to the brake pedal switch. On my 02 WS6 M6, there were two connectors off the brake pedal switch. One 3-wire and one 2-wire. The two wire connector had a blue wire which had no voltage unless the pedal was depressed. This is where I tapped in with the sole scotchlok that I used during my install process.
After tapping into that wire, the BMN switch shows light ON with the pedal is depressed, and light off with it at rest! So I'm good to go... tonight will be finding the proper location for the tach signal...
Let me know if this helps.

yes thats it I responded to your post on Tech. Matt at HSW said the reason why my nitrous activation switch is not lighting is because my brake wire isn't hooked up. That makes no sense.
1. I know someone that is using there BMN WS without the brown brake wire hooked up.
2. My red light comes on but my green light doesn't when I go into the "window".
3. See if you can get the power light on and the green light witht the brown disconnected.

The brake wire is only to tell the box when to reset the 1st gear lockout feature, correct? How could that prevent the tach light from working properly? Have you contacted BMN yet?
