Are there any other constant +12V wires besides the one in the ignition switch harness?

 

Left kick panel should be in there with the other feed lines to the ignition. Solid white if i remember correctly. Heavy gauge wires

Power seats are always +12Vs, dome lighting as well

 

That's the one I was talking about.

Is it possible to buy a "create a circuit" and tap into a unused slot on the fuse box? Is there a unused slot that has a constant +12V?

 

I know for the CL, Acura provides 4 different connector points. They are numbered 24-27. Each one has power under different conditions. Such as power on all the time, power on when engine is on, power on in accessory mode. Does the TL have this also?

 

Not sure why not. Even if you can't use the 'create a circuit' in an unused slot, you can use a 'create a line' in a used slot as long as you don't need more than an additional 10 amps.
