Ford Perimeter Plus...?
Just to update the thead in case other 2020 owners are doing research.
My truck is a 2020 XLT with the 302A package. Since it has different content than my friends 2018 XLT with 302A (e.g. my friend's 302A included remote start key fobs), I'll describe the features. Under the Advanced Settings menu, the truck has the remote start menu enabled from the factory with options for climate control (auto, last setting), seats (heat), duration (5, 10, 15) & a check box for system. The 2020 has the remote start system enabled through the Ford Pass app - use the iPhone to unlock, start/stop, lock. I wanted the Perimeter Plus because I wanted the ability to use the key fob for remote start like I did with my old SuperDuty. The shock sensor function was a added bonus for me.
I bought the 'Ford Perimeter Plus Vehicle Security and Remote Start System' (KN1Z-19A361-A). I didn't want to spend $60 on a piece of aluminum (bajamod - bracket & shipping) but wanted to utilize the shock sensor. I used the supplied zip ties to attach to the electronics block (metal bracket side) just to left of brake pedal. The bracket that the oem electronics block uses has a couple of ribs sticking out. I used some foam tape between the ribs to hold the Perimeter Plus in place while contorting myself into a pretzel. Once zip tied tightly, the ribs are in contact with the back of the Perimeter Plus. Wired everything up, including the jumper, and everything works without additional programming.
Hope this helps others with 2020's.

The truck have built in alarm no sensor and that’s what I need.
also came with remote start.
Sorry missed that part including jumper, I’m all set have the kit for a while.
also have Security Led, trying to find the best spot to install this.

Found several threads on this topic, I learned a lot from this one, so thought I'd ask here first.
Just bought a Ford Perimeter Plus shock sensor FS7Z-19A361-A (could have gotten FT4Z-19A361-A but made a judgement call on convenience).
1) I'm curious if there is a better/preferred orientation? There's no mention of this anywhere I've seen. Does it make sense that there might be a difference in performance depending on orientation (horizontal, vertical, which side up, etc) as well as the manner/location it is installed (tight, firm, loose, metal body, wire harness, etc).
2) I'll get a blue LED, but I think I still need to buy the Ford LED and splice the blue LED so it can plug into the module?
I had this (version of this) in my 2009 F150. It went bad after about 13 years and would randomly activate. It had the red LED mounted on the bottom edge of the dash to the left of the steering wheel by your knee with some sort of black dedicated plate/holder so it was OE in appearance but almost invisible unless it was lit up. Out of the way and no drilling.

No in fact I found a metal bracket up under the dash near the steering wheel to the right of the OBD II connector that it slid neatly into so I attched it there. it is flat with a slight inclination.
Don't bother before long you'll forget it is there until you or someone gives the truck a sharp bump.
See reply above
Quite awhile back I installed a JS7Z19A361A perimeter plus. From what I understand the first 4 digits are for the year it came out or the part number was updated, likely no difference. I was more interested in getting the remote start the impact alarm was a bonus. Don't forget about the jumper.

I'll see if my 2017 remote start, console shift truck has that or another metal spot to tightly secure. Not interested in making the "brake bracket". I've got an OBD2 splitter with AMP steps and Banks PedalMonster/iDash, so there's some stuff jammed up in there.

[QUOTE=GunnarzF150;7808425]I installed this on my 2017 with the AMP power steps and had a problem. The steps use the OBDll port, after a few minutes the steps will reset, a quick move to go down then right back up causing enough of a shock to set off the alarm. It doesn’t happen all the time but enough to be a problem. Just be aware incase it seems to go off for no reason.

Hope I don't get those issues with the AMP steps, that will be a bummer problem.
I don’t have the optional LED, but I realize it’s not necessary, the value of the sensor alarm is to discourage people and draw attention.

I think I’m going to make a small aluminum L bracket and attach to the left side of brake with one of the existing bolts (shown).
There’s already another bracket holding something there (shown). And the under dash pocket is filled with an ambient lighting module. The only other place is the exposed metal above the kick panel, but not sure what’s on the other side of the metal body wall.
