Parking lights only?

On my 2006 Tacoma I have off/parking lights/headlights dial. Parking lights and headlights dim my aftermarket radio and turn the backlight on for controls.

I have aftermarket headlights that have "DRL", but it's just the parking lights

So, I was wondering if it's possible to have the parking lights be on without the radio being dimmed and the controls being backlit. I only want the radio dimmed and the backlights on with the headlights.

Has anyone done this? Or can anyone point me in the right direction?

 

Snip the dimming wire of the connector to the radio (cap the harness side) and attach it to relay that is activated by the steering wheel headlight connector (Low beam)(it's a negative trigger)

 

What about the dash lights, ac lights and license plate lights?

 

Just this then. It handles the dash illumination (all) including the radio.

 

would you mind explain what to do in caveman terms?

 

On connector 1J slots 7 & 19 are the dash illumination wires (+), this connector is located on the rear of the box that houses the cab fuses.
How so far?
