Hello!

I would like to ask if someone know where to find a voltmeter wiring guide.

I want to install a voltmeter gauge in our R56 but i don't really know what cables to use.


Thank you!!!

 

You can get power from under the center console at the cigar lighter/accessory port.

Or just buy one of these -

 

Hello danjreed!

Thank you but that 12V meter feels like a temporary solution.

I will try to install a gauge beside the rpm gauge.
Just need to open up the dash board cover under the steering wheel. Lets see if i can find some interesting cables.

Or else maybe i can wire from the RPM gauge? I don't remember but it had some cables in different colors. Need to google that.

Thanks =)

 

Hello!

Yes you are right, i think getting power from the center console is the best way to go.

Do you know where i can find a guide on how to remove the plastic ?

Thank you very much!!

 

The center console is super-easy to get to and will automatically turn off when the power goes off. Safety first: disconnect your negative before doing any automotive electrical work. Cravenspeed has a great guide here: http://www.cravenspeed.com/product_i...wiring-kit.pdf

Alternatively, you could run a line straight to the battery through the firewall, but the gauge will trickle power no matter what. If you go that route, make sure it's fused close to the battery in case there's ever a short.

 

Hello dear Krashlocke!

Thank you very much, I used this guide to do it:

One last question, if you are going to use power directly from the fusebox, how is that possible?

Thank you very much for helping me!!

Take care and drive slow.

 

If you're running off of the 12v accessory circuit, there's already a 15amp breaker in there with plenty of overhead. Consult your user manual for which is which. Don't draw more than 80% of a circuit's rated fuse voltage and you'll be good to go.

If you're connected directly to the battery, you would want to install an inline fuse like this:


... then connect the rest of the circuit to the leads. The factory fusebox isn't a player. That's a real overkill way to do it. I strongly recommend just using the accessory circuit, unless you're installing something with a lot of power draw, like amateur radio or a powerful audio system.
