I am installing a 99TL HU in an AH and am looking for confirmation on my wiring. My objective is for a simple installation and, presently, intend to use the following "A" connections:
A2-Switched Power,
A10-Constant Power,
A9-Dash Light input,
and (2) front speaker connections.
Presently I am not sure whether A9 or A19 should be connected to my dash light circuit and I would appreciate your confirmation on the correctness of my choices.

After reading another thread, I am concerned that I may also need an equalizer for the system to work. Is this true or can I get by with just the HU. I am not using the external subwoofer amp and will only be driving front L/R 4Ohm 5.25” speakers.

With the noise of this relatively loud 1964 British sports car, I am not looking for elegant sound but just to hear something other than my own thoughts.

I would appreciate any suggestions.
