Battery Cutoff switches ? post your setup

[philooo]

ok so after looking at some options, I think I have 2 choices to make:

V1: CUT EVERYTHING
I cut off everything at the positive side of the battery, but then I don't control where the potential alternator spike will go. Hopefully it will not blow something in the electrical system before going into the resistor.

V2: CUT WTH HELP OF IGNITION SWITCH
I follow more closely the switch manual and tap into the alternator wire more specifically, which will guarantee the potential spike will go only to the resistor when switch is off. And use the other switch pole to cutoff the ignition wire.
Result is that same but the electrical cutoff is similar to removing the ignition key. There is still power in many wires around the car, even though the car will be stopped.

Anybody has opinion on the which way to go ?
see my schemas attached, an also the 3 pages of the electric manual relevant to the install.

Hey Philoo - Did you ever get your kill switch successfully installed?

I'm trying to work out installing a Pegasus 4430 kill switch with the alternator protection contacts seen here:

I have it all figured out except for where to splice in the ignition wires - one side goes to the switch, and the other to the coil. After an hour or so trying to make heads or tails of the wiring manual pdf - I'm even more confused lol...anyone have any insight into which ignition circuit to cut the switch into?

Just FYI for people, when setting up a four prong switch, set the main posts for battery hot, set the two small posts to the RED/BLUE wire on the alternator. ( Cut the wire and run one half to each side to the cut off.)

@Philoo
I would like to know also. Where on OE harness is best place to tap in?

I don't know how useful this is to you all, but this is how mine is set up. It worked when my car was stock ECU and it works now with my Haltech.

Short story is it interrupts IG2 MAIN fuse, wires enter the fusebox where the big trunk of cables does. It cuts power to the ECU but leaves the keyless entry and other stuff working.
