Upgrading battery warning light on 2013 predent.
I want to upgrade the amber warning light on my 2013 precedent to a meter type indicator to get real time battery status. The amber light only comes on when batteries are low. I would think that the real time switch would have to have a constant flow of power to get reading. How does the new meter hook up to the factory wiring? Also, I need it to work behind the ignition switch. Thanks.

a simple two wire digital meter (with numbers) is simple + to the back of the key switch and - goes to the pack negative . I did not use the battery light wiring at all.

Yeah, the warning light wiring is triggered by the OBC. Use Sawn's suggestion. :thumbup:

Swan, did you pick up negative from existing wiring in dash or run new wire all the way to the batteries?

Re: Upgrading battery warning light on 2013 predent.
There should be an existing negative black/yellow wire available in the Precedent dash area for the meter negative connection.

I bought digital meter and after opening 2013 Precedent dash and probing all the wires around key etc could not find connection carrying pack voltage. Anyone have good picture of wires that carry?
