Somewhere I thought this was discussed recently but I couldn't find a thread through search. I would like the both side view cameras to come on the main display even when no trailer is attached. I know whatever is connected to the trailer connector has to have enough resistance to get the truck to think a trailer is attached so something like an LED lighted receiver mount such as an American flag won't work. Google Gemini mentioned a Hopkins type light that has an #1157 bulb would work.
A couple cheap options it mentioned was using a 2 watt 100 ohm resister (ordered off Amazon for around 10 bux) wired across the ground prong and the taillight prong of the 7 way or 4 way trailer connector would work if headlights are turned on all the time.
The second option was to go to an auto parts store and get a pack of two 50 watt 2 ohm resistors for around 10 bux that are used to fix turn signal flickering. Then wire one from the trailer connector ground prong and left turn signal prong and wire the other to the ground plug and the right turn signal. I assume having the headlights on shouldn't matter.
I also was advised that trying to mimic a trailer being towed would shut off the backup and cross traffic alerts when backing up.
I have a 7 way trailer plug adapter I could probably wire up like second option but thought I'd ask for other opinions before buying anything. It's not something I would use 24/7 but there are a few situations where I'd like to see along side and behind while turning such as changing lanes on the interstate.
Thanks
