• Hi everyone,

    As you all know, Coffee (Dean) passed away a couple of years ago. I am Dean's ex-wife's husband and happen to have spent my career in tech. Over the years, I occasionally helped Dean with various tech issues.

    When he passed, I worked with his kids to gather the necessary credentials to keep this site running. Since then (and for however long they worked with Coffee), Woodschick and Dirtdame have been maintaining the site and covering the costs. Without their hard work and financial support, CafeHusky would have been lost.

    Over the past couple of weeks, I’ve been working to migrate the site to a free cloud compute instance so that Woodschick and Dirtdame no longer have to fund it. At the same time, I’ve updated the site to a current version of XenForo (the discussion software it runs on). The previous version was outdated and no longer supported.

    Unfortunately, the new software version doesn’t support importing the old site’s styles, so for now, you’ll see the XenForo default style. This may change over time.

    Coffee didn’t document the work he did on the site, so I’ve been digging through the old setup to understand how everything was running. There may still be things I’ve missed. One known issue is that email functionality is not yet working on the new site, but I hope to resolve this over time.

    Thanks for your patience and support!

I am installing an Innovative Motorsports Air Fuel Mixture gauge and I need a ground and a switched positive under the dash. They suggest not using an ignition ground to avoid a "noisy" source. Anyone got any suggestions?
 
Br/W off ignition switch is switched positive with the key. Nice wire to work with. If you want to run a high current application like a light or grip heater, send this to a new automotive relay and large positive fused wire from battery. This is very clean. Battery ground. I used this wire and relay to power a GPS. Did not really need the relay but thought I might add lights later. Head light wire may run a/c as well as 12v d/c and not be "clean" enough.

This is from a 2010TE schematic. The Br/W goes to all the relays. I could not find a 2011 511 schematc. BMW might have changed the colors.
 
Suputin, I've been studying to make my post more helpful. There are apparently 6 wires coming from the ignition switch. The 2011 schematic only shows two. The Y-R is hot from the battery. The Y-Sb is switched positive to the RH starter switch. This should work for your purposes especially if you use a relay. One of the other wires may work and maybe even better but I just can't find any more info for you. Let us know how you wire it. Good luck.
 
I ended up using the circuit that runs the headlight running light because it was easy to access and tap into. For ground I went to the steering stop bolt on the frame because it was close by and easily accessible.
