That's cool, please keep us updated - with pictures if possible...!
OK, maybe I'm missing something.......like where are your instructions? What do I do?I did this to my 2019 Honda Passport Elite and it works great. Read to link below several times to let everything sink in. The 2019 information is towards the end of the link article. Parts are very common and readily available. Parts procurement is referenced in the link.
The link: Automatic Auto Idle Stop System set to Off by default ver 3 (Detailed) (see post no, 20 by MtMan in link).
12V brown wire info:::: use the 12v on the console accessory plug. The diagram is absolutely correct. For everyone that hasn't done this yet, the brown wire is located on the bottom of the console- (see post no. 27 by synstsia in link). also referenced below.

This is where you get your 12v+ from.

This is how to wire your board to the wires. FRM01 board,
View attachment 5455
This is the plug that connects to the Auto Idle Stop button in the console and the plug referenced above in the FRM01 picture.
The FRM01 board is a programmable board. When you push the start engine button on the car the board will wait 5 seconds (programmable) giving the engine time to start, then click the relay on the FRM01 board for 1 second which is the same as you pushing the Auto Idle Stop button on the console. The Auto Idle Stop buttons on the console still works to activate and deactivate the Auto Idle Stop features of the Passport.
If that works, I'm in, I really love that feature on my wife's Lexus...!A chart, with 18 section programs came with my timer and there is a CH1 connection port not being used. I wonder if I can connect it to my side folding Mirrors, so they retract, when power is off and swing out when I start the car.
