Perimeter Lighting

[Bert Remington]

After purchasing my used 2020 XLT, I immediately installed the AutoStart/Stop Disabler.  I wanted to understand how it worked and was also thinking of installing a dash cam so I purchased the Wiring Diagrams manual.  The TC is very much a CANbus vehicle (it has three).  So I explored and found items of interest in Section 140: Customer Access circuits and Upfitter Generic Function Module.  A bit more searching revealed the GAM is a nifty interface to the CANbus network and it is programmable with 9 inputs and 15 outputs.  Judicious GAM wiring and programming enables sequencing with delays, etc. Cool!

 

One of the safety/assistance features of more expensive passenger cars is perimeter lighting that illuminates the terrain near the car.  Very helpful for us old folks to spot curbs, vegetation, etc trip hazards in the dark.  And there's the bling!

 

So I'm thinking of a multi-step process.

 

First would illuminate the headlights/foglights and backup lights as well as the current lights upon certain keyfob presses.  The lights would stay on for maybe minutes rather than a few seconds.  Same with interior lights.  Turning them off would be maybe 60 seconds after all doors closed or when the engine is started.  These functions require programming only, no wiring additions except for delay relays connected to the GAM.

 

Next would be added external UnderGlow lights along the sides and ends tucked under the bodywork.  Wiring additions required from relays commanded by the GAM.

 

Last would be additional interior lights under the dash (for front passengers) and the front seats (for rear passengers).  Wiring additions required from relays commanded by the GAM.

 

For powering the additional lights it looks like the F43 15A circuit assigned to the Taxi Roof Lamp would be a good choice.

 

Thoughts, suggestions?
