NAVI/AUDIO wire sizes

[nikey22]

what are the general sizes of wires for the harnesses. Specifically CONNECTORS A, B, C, E.
If anyone has a chance, take a pic of the harness near the connectors

for example - 2012 LX/EX-NAVI:
CONNECTOR A - has white and black wires for power - 12V battery, they seem small caliber for the job.
CONNECTOR B (NAVI) has B10 and B20 for powering the NAVI screen, again - 12V, yet they seem smaller than the A connector wires.

I've also thought 12V battery wires should be larger.

What are you trying to do?

just need to figure out AWG wire sizes are being used for 12V power/ground. I surmise that they would be pushing 10A, since the NAVI/RADIO fuse is 10A.

Its interesting that the holes for the power/ground wires on the A CONNECTOR are larger than the rest, yet for the B CONNECTOR (which powers the navi screen), appears to be a smaller gauge... maybe less amperage needs to be used there??

Will need this info for NAVI install.

@iShift_6 may know this info as he had his out just recently.

I will double check at work today, but I think the main audio power is 16 gauge wire.
Can't speak for the rest but I would assume they would be 18 or so.

As for their gauge selection, this is all speculation here, but the stereo doesn't have an amp in it (Ex-L).
So it is not pulling a great deal of amperage, so there is no need for a higher gauge wire. If you look at the amp
power wire, it is probably a higher gauge perhaps 14 or 12. My guess is 14 or 16. It's been a while since I did my
amp mod, and don't remember the wire gauge.

Hope that helps a little

yes thank you, it helped.
When I open it up to do the mod, I will compare the existing wire gauge with known sizes.
I'm looking at some website to help choose the correct wire size for a 12V DC circuit, knowing that the NAVI/AUDIO system is 10A fused.
