Excellent - and thank you both for your past helpful posts.

Cheers onebob

The one I fitted has been without fault, seems accurate through all speed ranges, can be fiddle with the switches and find a long straight road to do the adjustments

Great news, and from the feedback all that i hear are happy customers - which is comforting cos mine is already on its way to me
I’m hoping that odometer accuracy is returned as well as speed - SF mentioned earlier in this thread that the odo and speedo used the same pulse signal.

Just finished installing my C6100 yesterday. So far so good, is accurate with the gps at lower speeds and reads slightly high at 100 and above, which isn't a problem, just means 110 on the Speedo = 108 ground speed. Neither here nor there.

I read both slunnies install and another one which are essentially the same, and both installs grab power from the driver side fuse box.

I couldn't see the sense in this, and just powered the SCU from the ignition feed (and ground) into the SLABS ecu.
Neat, convenient, all wrapped up in a nice little package

Yes ...x2 that’s my approach as well - they say great minds think alike

I will use pin 2 LG (light green) wire on connector C0504 for power a source (it goes back to fuse 28 in internal fuse box) and for a ground I will use or create a nearby body earth because although Pin 12 is fed by a black wire (a colour commonly used for earth wires) this particular black wire goes back to the diagnostic port and I’m cautious about interfering with the diagnostic circuit.

Apologies, the link to my installation guide had to change due to a crash. It's now at

We grabbed the feeds from the Drivers side because the truspeed has selectable settings (dual switch).
Both of us mounted the box behind the drivers panel allowing a quick and easy change when swapping tyres over.

I can see the logic in your install with a set and forget box.
