Ignition Kill+MFI

I installed the MFI last year, and love it. I also have the JC Whitney hood lock, which has the ability to ground a wire when locked (For a starter kill). Since I have a 5-speed, I had it hooked up to the ground side of the coil, which worked great. Now since MFI, I am reluctant to do the smae again, due to the computer control. My Question is: Where should I hok this up to disable the ignition system of the jeep? I don't want the starter kill, as it is too easy to bump-start. Any ideas?
TIA!

Re: Ignition Kill MFI

I'd probably either put the kill switch on either the power supply for the computer or the computer ground (I don't see how that could hurt the computer considering the power normally gets switched on when you turn the key anyway)... No fuel, no drive, so that's my vote... [img]/wwwthreads_images/icons/crazy.gif[/img]

Re: Ignition Kill MFI

Thanks, but when you kill the computer, it needs to "learn" again, takes about 30 min. It has a hot to the battery.

Re: Ignition Kill MFI

[img]/wwwthreads_images/icons/blush.gif[/img] I forgot about how those computers need to do their learn thing... [img]/wwwthreads_images/icons/crazy.gif[/img] How about the fuel pump? Same basic thing, can't be push started without that working either... Hmmm How about a combination of weird things like that... Take away the fuel, spark, and start signal from the ignition switch, and it'd be fairly likely to stay where it's put... I believe CJDave mentioned having some tricks he had to keep your Jeep where it is... Hey Dave (or whoever that was that had it), if you're listening, would I qualify to get that info from you? (The basic concept would be about the same in a GM truck as it would be in a Jeep, wouldn't it?) [img]/wwwthreads_images/icons/crazy.gif[/img]

Re: Ignition Kill MFI

[img]/wwwthreads_images/icons/tongue.gif[/img] I hear you sand guy.......and ....my drive-off prevention can be easily adapted to the in-tank fuel pump as well, AS LONG as the fuel tank has a return line. Have MFI e-mail me and I'll explain it privately. I developed this system for an anti-hijack setup, but it works the same way.[img]/wwwthreads_images/icons/crazy.gif[/img]

I never believe any statistics unless my moonguys [img]/wwwthreads_images/icons/crazy.gif[/img][img]/wwwthreads_images/icons/wink.gif[/img] made 'em up themselves.
