M1 Ignition Line

**gleinz** · 09-27-2005, 11:20 PM

Sorry for not doing an exhausting search, but it's late, I'm tired, and it's a stupid question so I'm sure I'll get a quick answer.

Just wired up the M1-ATX psu, powers the computer and all, but I have no startup/shutdown controls. Now my problem is that I don't know where to wire in the ignition line. I thought I could just tap into the fuse panel, uping thinking about it more that would just be like a remote turn on.

So in short, where do I need to connect the ignition line to the psu? I have a 2004 WRX if that helps.

Thanks, and don't flame too hard

If I were you, I would just connect the switch wire from the positive on the battery. Then just run a small wire (I used network cable) to an start/shutdown button up front. If you take too long getting petrol or anything, the damn computer will shut down. Then just use the power settings on the PC to standby or hibernate after not being used for a while.

The ignition wire goes to any switch 12v source, i.e. a 12v source that is only on when the key is turned to the ACC or ON position. On most vehicles, you can tap into the 12v for the stereo (assuming it's on a switched line, of course) or a cigarette lighter. You can also tap into a switched line from the fuse panel.
The M1 senses power on this line and will start up/shut down the PC.

This is ridiculous advice.
The M1-ATX has a times shutdown controller that will leave your PC on for a period of time. It's set by a jumper and the settings are outlined in your user's guide.

Alright, I did some more searching this morning... I'm tapped into the ignition fuse in my fuse panel, so I guess it's just my jumper settings. I only use the jumpers on the bottom row of pins, correct? I'll check it out after work.

Thanks for the advice

Pay attention to switch polarity for J8 and J6?(the main guy) these two are in parallel. Jumper settings mostly (only) affect shutdown stuff IIRC.

Ah... I see my problem. I forgot to connect J6

This is not ridiculous advice if you would like to take the keys out once in a while (like for someone to get in the house?) and still tinker with the PC. Or what if you want it to just stay on for a couple of minutes, but then your trip to the petrol station, or inside the house or whatever is longer than expected? Gotta wait for a reboot.
Its easy enough to set up either way, but its easy to press a button on your way into or out of the car - its not exactly easy to take the machine apart every time you want to change the jumper settings to suit your circumstances. The timed power settings in windows make sure that hibernation stops your battery getting too low.
I have an M1 and I am well aware of how to set it up, but after using the jumper for just a few days I then ran the on switch to the dash.
Everyone loves a big red button on the dash too. People always assume its something 'special'.

Ok, no arguing!

Anyways, I'm just really really stupid and didn't connect the mobo on/off switch. All is working great now!

sargatlarge - to avoid shutdown at gas stations or other quick stops, just keep the key in the ignition. This will still have the ignition line on, and it won't shut down the PC. But I also did install a switch as a safety measure, just until I test out and make sure that the M1 doesn't drain my battery

Thing is, I need my key to open and close the petrol cap and I need to lock the car shut when I go and pay so that theives dont get in.
I just dont like being patronised by people with a different opinion/circumstance! Some technies - they have a chip on their shoulder
