Electrical Wiring Question
Okay, probably not the absolute correct forum to post in, but it's indirectly related to audio systems.
Long story short, my Kenwood navigation unit has been acting up and the factory can't find anything wrong with it. As a precaution, I would like to install a switched 12V feed directly from the distribution box or other suitable location rather than using the factory harness as I suspect power may be an issue. I would run a fused feed right to the battery, but I would like to have it switched.
Now, the questions: since the underhood distribution block is likely constant power, is the interior fuse block the best place to grab a circuit? If I was to use an "add a circuit", what circuit(s) would have the least load on them normally?
Failing everything else, I'll probably do some probing around with my meter and if that doesn't tell me anything maybe a service manual would be in order?
