• There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Color of wires needed for volt meter

Im getting ready to remove my fuel gauge and temp gauges from my 2014 RTS...I would like to put the volt meter in the left panel in place of the gas gauge...Does anyone know the exact colors of the + & - wires I need to use??? Also, anyone that put the volt meter in the right side in place of the temp gauge, what were the exact color of the + & - wires for that side???

I plan on putting a air gauge in the right side in place of the temp gauge...I will be making my air pressure manually adjustable using the dash switch...NO MORE constant automatic exhausting and pressurizing the air bag with every movement of the bike...One side of the rocker switch will activate the compressor and the other side will activate the dump valve...If we are riding double and I like the ride with 70 lbs of air, I will set the dash air gauge to 70 and ride...If I want more or less I will change it...I'm tired of hearing the compressor cycling on and off...NO I DON"T HAVE ANY LEAKS...I HAVE LEFT IT SET IN THE GARAGE FOR 2 WEEKS WITH 80 lbs and the only air it looses it what is lost checking the air...larryd
 
Dont worry about colors. The ground is the center wire in the plug that goes to the OEM gauges( i think its black BTW ). For power, use the wire with the female blade terminal on it. It is 12 volts and powered the light in the OEM gauge It is the same on either side. I used a screw and attached my ground wire to it and pushed it into the OEM connector. Then used a male blade terminal to plug the power in. No wires get cut.

I hope this is a digital voltmeter, because the analog ones are pretty much useless.

And then, are you asking which existing wires to tap into to power the voltmeter ??
There might also be a back light involved.

As far as wires going to the meter, + is usually RED and - is usually black.
 
My reading of the 2014 Roadster Shop Manual Supplement schematic:

FG (Fuel Gauge):
FG1-S Bu is signal from sender
FG1-G Bk/Vt is ground
FG1-P Og/Rd is LFB F7 +12V
FG2 Og/Rd is LFB F7 +12V

CTG (Coolant Temperature Gauge):
CTG1-S Bg/Bk is signal from dashboard cluster
CTG1-G Bk/Vt is ground
CTG1-P Og/Rd is LFB F7 +12V
CTG2 Og/Rd is LFB F7 +12V
