djskeme Posted June 24, 2007 Share Posted June 24, 2007 Hi guys, I have a car pc built into my supra and its all working well. Only thing is, I want it to boot up quicker, and to achieve this think the best solution would be to wire the boot cable to the central locking...or alarm fob. that way the computer will boot when the car is unlocked, and shut down when locked. Does anyone have any knowledge of Toad alarms to tell me which wire I need to run from it and whether I need a relay to do this? Many thanks.

Sandy-m2 Posted June 25, 2007 Share Posted June 25, 2007 hold on i'll upload the documents Quote Link to comment Share on other sites More sharing options...
Sandy-m2 Posted June 25, 2007 Share Posted June 25, 2007 oh crap i've left them at home. i have the answer for you as i wired my mirror flip into this, the only problem is that the allarm uses a negetive pull to activate things, ie. it pulse negative for a time or it it pulls negative constatly when active/deactive. You will probably need a box that interperates the pull of the allarm signal to boot the pc. I'll bring the documents tomorrow. Quote Link to comment Share on other sites More sharing options...
ukApache Posted June 25, 2007 Share Posted June 25, 2007 the brown/white wire pulls to ground when the alarm is activated. use this with a SPCO relay and that should do the job Quote Link to comment Share on other sites More sharing options...
djskeme Posted June 25, 2007 Author Share Posted June 25, 2007 thanks for the help guys. Might be a silly question, is the brown/white wire hard to find?? If i connect that, through the relay you mention to the ignition live wire of my car pc setup then this will do this business yeah?? Quote Link to comment Share on other sites More sharing options...

The toad alarm has a separate box with all the wires coming out, don't confuse this with the siren that's under the bonnet. Are you familiar with how relays work?

BASHTHEBISHOP Posted June 25, 2007 Share Posted June 25, 2007 I am a complete noob in terms of car wiring BUT based on my PC knowledge(not a great deal either tbh) wouldnt this be a bit dangerous? Say you disarm and rearm the car again a few times in quick succession, could this not fudge the PC? or could you build a UPS unit into this to aid this problem?

merckx Posted June 25, 2007 Share Posted June 25, 2007 I was also thinking that with most pc's you have to shut them down in a specific way and not just turn off the power supply, or can this be done if they're setup correctly? Quote Link to comment Share on other sites More sharing options...
djskeme Posted June 25, 2007 Author Share Posted June 25, 2007 Hahaha, yeah...im a pc tech - dont worry about that guys! its the car stuff that im useless at! My carputer has a specific shutdown/startup controller which doubles up as a 12v power supply. It works around engine cranks and always monitors the battery life to stop flats etc. where is the toad wiring box normally located? I found a box behind the radio when i put the screen in....but i couldnt honestly say whether it was the toad one! :$ Quote Link to comment Share on other sites More sharing options...
