TPMS emulator?

Picture of the connector?
Apologies, I found it as 20791502

I'm glad I did a little more research because I had my USB converter on the lower left spade, which is actually RAP. I moved it up one which is 10A switched with ignition.

At the moment I'm just shoving these insulated female spades on the tiny male spades. It "works" for low-draw accys but it's hokey.

Here one is connected and one (red wire) is disconnected:

I've got the proper connector on order. Knock-offs are surprisingly plentiful and I'm gonna try one.
 
The subarus you get a little yellow flashy flashy then solid.. and a tpms malfunction pops up on the dash for about 5s.
I can deal with it.

The jeeps boy they were mega naggers.. beeps boops bonks chimes flashes messages popping up.. ugh.

The only reason I never ran winter tpms on subies is the computer would only hold 1 set of tires in memory making it a pain.
IIRC since 22-24 depending on subaru model the new systems hold more and auto recognize them more like the jeeps.
Jeeps.. auto register and auto detect boom.

Yeah, every vehicle is different. '04-08 F150 just flashes the TPMS light then leaves it on solid. No noises and the light is small.

But an '06 Expedition does a shrill beep at start-up and requires you to clear the message every time. Ditto for this '08 GMC actually.

I'm considering one of these emulators for my mom's '18 KL Cherokee. Every morning when it's cold it says all four are too low. She understands it's because of the temperature but it still causes her great anxiety to see "error" warnings.

Some of the TPMS brands out there can be cloned, I think the Autel MX one for sure can. So if you don't want to deal with TPMS pipe bomb and the compatibility, not waking up, leaking, lawsuit, etc. You can give the Autel MX a try. Last year I bought a set of these Autel MX sensors and went to America Tires, and they programmed it wrong once after tossing away the old one, and just get the reading out of the ECU with their tools and clone the Autel MX sensors based off what the ECU was expecting. Pepboys try to gouge me by charging mount / remount whereas America just pop the bead to replace and put it back on, and charge me like $10 to program.

You can even "lease" a tool from Amazon to read from your existing ECU or tire, and program Autel's MX sensors, yourself if you don't want to go to a tire store.

That is an option but an unnecessary one for me. I assume you hit reply in general and not to anything I said specifically?
 
After a little mental wrestling I got my Spooftpms emulator to work just fine on my GMT900. No TPMS dash light, no messages about checking tire pressure on this or that wheel position and no more fussing with dead or dying sensors. I opted for the 12v version. Great customer service/technical support by email as well.

After a couple weeks this GMT900 was giving TPMS warnings again. I haven't had a second to look at it. I'm hoping it was my pathetic power connection. I have the proper connector sitting here so someday we'll see.....

Quoting myself, I don't think anything was really wrong with this emulator as it resumed normal operation. The one time I did see the TPMS warning I think I just went KOEO, or maybe I briefly started it -- can't recall.

Best guess the battery in the unit fades with prolonged sitting, and this truck isn't used everyday.

I don't know, but it's fine. I did wire it properly through the MBEC, although my previous McGuyver connections were solid (enough)

Inexpensive Chinese MBEC connector:
