1 Motogadget M-Unit Blue Install Fri Jun 30, 2017 12:23 am

So, I was having trouble with the electrical on the K100 project and in frustration let it sit for a few months. A couple nights ago I decided it was time to get back to it, and in doing some research, I found the Motogadget M-Unit, a solid state circuit breaker with integrated relays, programming, and a whole lotta other jazz. I decided to drop some money on that instead of finding somebody who actually knows what they're doing. In anticipation (it comes tomorrow), I started pulling out unnecessary stuff (like the fuse panel, flasher unit, and bulb monitoring unit) and figuring out how this install is going to work. Since I've also changed out the gauges, the fuel level sensor is going away, at least for now.
The first of many questions:
I can get rid of the fuel injection relay and hook up to the power bar on an aux circuit. The fuel injection relay is switched by the ignition control unit and, when closed, sends power via two wires 1) to the fuel injection control unit (and injectors, etc.) and 2) to the temperature sensing unit -- the latter via fuse 6 (which also powers the fuel level sensor). Thus, I could simply connect one of the two output wires on the fuel injection circuit directly to the temperature sensing unit (which I gather I will need to keep). This leads me to wonder why the temperature sensing unit is powered by the fuel injection relay in the first place. Would I have to keep it that way, or I could I just hook the temp unit up to an always on aux out port? Assuming that I draw power for the temp unit from the fuel injection circuit, I assume that I should put an in-line fuse on that wire? Assuming I do that, I might be able to keep one aux circuit open for a fuel level sensor down the road.
Any advice is appreciated.
Cheers,
Frey
