Any suggestions/diagrams how to proceed?

On a HEI system, the TACH terminal gets connected to ground with the remote switch and prevents the coil from firing. A more sophisticated system might involve a timer that lets the engine run a few seconds, then shuts down the ignition system. With some basic electronic knowledge and a couple of relays, a system can be designed to blow the horn and flash the headlights after the engine stops until the battery runs down or a cable gets disconnected.

Simplest route is a hidden switch, maybe one like this one from Speedway Motors that can cut the battery & ignition. Mount up under the dash wehre it's hard to see or in a fender, so long as your hood locks it's pretty hard to bypass. I've seen simple circuts that use relays powered by a hidden switch that cut the battery and ignition circuts, or a variation on the theme that require you to turn on the key then pass a magnet over a hidden reed switch to engage the relay, shutting off the key resets the whole thing. 1956 GMC 370 dump " 'Tater "1970 VW Volksrod "the Black Bomber" 2007 Chevy Avalanche 2020 Jeep Cherokee Trailhawk, 2005 Harley Davidson FLHTCUI I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans. Being unable to appreciate them all is missing out on a world of great things. But thats just MY opinion! :P

The ignition and/or start circuit goes through a jumper wire in the phone jack, and once it's removed, turning the ignition key has no effect. The female socket can be located in a hard-to-see place to hide its real purpose. Jerry

I thought a cable lock might work, but have not figured it out yet...? | | | | | Joined: May 2010 Posts: 89 Wrench Fetcher | | Wrench Fetcher Joined: May 2010 Posts: 89 | if you know how to hot wire? then it's easey. just install a swicth to open the curcuit to the pos. side of your coil after your ignition switch. Hence no power to the pos side of the ciol no start.
theres a tool for every job,and that tool is a hammer. it's easy to give advice if it's not your pocket book at stake. A well thought out plan,Is nothing. Untill exacuted twice.

I run it up behind the hood latch then down around the grille braces in front of the radiator. However GMC's allow a bit more room for reaching into the grille, so for your chev you may ned to get more creative. On my '65 Chev I ran a cable down to the frame rail so I could reach the lock behind the bumper. 1956 GMC 370 dump " 'Tater "1970 VW Volksrod "the Black Bomber" 2007 Chevy Avalanche 2020 Jeep Cherokee Trailhawk, 2005 Harley Davidson FLHTCUI I dig all cars, old and new, whether they were hammered out of American iron, German steel, or Japanese tin cans.

Tech Tips! what a good idea. There's a bunch of stuff I can do in there.
I like the lock idea, and I finished the hidden switch up under the dash this last weekend!
thanks for you help. | | |
