2019 Ranger with slide-in 7 pin connector lost blind spot detection.

[life_w_vagabonds]

So, I got an Alu-Cab Khaya for my Ranger. The camper uses the 7-pin connector to run brake, signal and backup lights on the camper. Really nice LED lights, that's the good news. The bad is because the truck thinks I'm pulling a trailer the blind spot detection gets turned off as well as the stop-start. Yes, I am one of the three people that thinks stop start is useful but that's another thread.

Another gremlin is the third break light on the camper is not working and I am told it will not work without a trailer brake actuator hooked up. Bummer cause that's another nice LED light, and I like LED lights.

Any ideas how I can fix any of these issues. Are there settings or software fixes or would it require rewiring? Not having much luck with the Google, most relevant adjacent information is about disabling stop-start, turns out you just need a camper.

Thanks

Humm... You can bypass the 7 pin plug and hard wire it directly to the tail/reverse lights.

I'm sure that you could mess with the settings in Forscan to have it do what you want, but I'm not too familiar with it so I can't say for sure.

Can't you adjust it to work on a trailer? Just tell it you have a really small trailer?

BLIS® with Trailer Coverage | Ford Co-Pilot 360™ Technology

If you drive a Ford pickup or full-size SUV and pull a large trailer, an enhanced version of BLIS® (Blind Spot Information System) is offered that provides coverage for your vehicle and the conventional trailer you're towing.

They call it "Blis" if there is anything under that in your manual...

My Blind Spot worked with my Airstream...granted I just got the trailer and and have only towed once, but seemed to work great.

Hmmm, seven pin connector? Assume you have a brake actuator.

Maybe disconnect the wires to the connector that are not being used by your camper?

Yeah - have a aftermarket break controller but that is not integrated into the programming in any way....just wired in.

You don’t have the ford brake system? On my ford, as soon as a trailer is plugged into one of the hookups, blind spot detection is disabled.

I think you might be better off to figure out how to wire this in without using the trailer hookup if the blind spot detection is truly important to you.

Update. Got blind spot to work. I was prompted by the truck about trailer size, changed the settings to lowest value. Works OK now.
