Source of +12V up front?

[Ryan Wright]

Hello again,

I've got the dreaded dim headlights up front and have purchased relays
to fix this. I'm looking for a solid source of +12V power up front
that I can tap into, both for the headlights and for a new audio
amplifier I'm installing. Any ideas where I might find this? I'm
trying to avoid dragging a new heavy gauge cable all the way from the
batteries at the rear of the coach.

If you can't think of a good source of power up front, any thoughts or
ideas on routing paths for a new circuit would be appreciated.

Thank you!
