If you mean a switch to isolate the battery, you can get one to put in-line with your positive cable from Harbor Freight for under $10., is you need to kill the ignition you can place a toggle switch and go from either the hot wire to the distributor and splice in, or from the ignition switch on the steering column at the plug connector, which is near the base under the dash on the topside. With a test light you'll be able to determine the hot wire pretty quick, This is also a good theft deterrent.

any body have electrical drawings for a 79 gmc sierra 1/2 ton truck

79 should have a HEI distributor ... look at the cap ... the single wire ... is the HOT WIRE ...



NOT the ones shown ... the wire at the end of the cap marked BATT ...

Doc here,

The wire plugs into the CAP at the BATT terminal, next to the terminal marked "TACH"...

If you install a kill switch, Be sure the contacts can handle the current..20 amp draw for a stock coil, up to 40 amps for a competition type..

If not rated , use a relay.

thanks doc. I am not to familiar with electrical systems.listen when you splice the wire,you cut the wire and add the third wire that goes to the toggle switch. It's that correct.thanks for your help.

Doc here,

The Kill switch goes in line with the BATT wire to the coil..that wire is cut, the side from the ignition switch (12 volts) goes to one side of the kill..and the other side of the kill goes to the BATT wire on the coil..no third wire is used.

Doc here,

Semper Fi Dude..

Was once one myself...and my son just got back...and out..

You could always take the ROTOR with you too as a back~up..most people don't look there anymore..

Or if you have a CD player with a detachable faceplate, you could hook up a relay to the remote power antenna / amp line for the relay coil , and the Ignition coil power and coil to the normally open and center wiper..

That way without the faceplate in place and the CD unit on..it won't start..The only drawback..you need to have the radio on (at least in mute) with the antenna powered up to drive it..

Not a problem in my case tunes are always on...whenever I drive..
