Kill Switch Engage (help?)

So after the headache of the attempted theft of Ramona, I have decided to install a kill switch (as well as a decoy or two) and a couple other theft-prevention measures.

So first: which is the better line to kill: starter or fuel pump?

Second: I am having a hell.of a.time with the wiring diagrams in my Haynes manual. Anyone want to give me a crash course on where to find the lines?

I already have all the parts and I know where I'll be hiding my switch. I am just a bit lost on where to splice in and which line.

Thanks!

 

I highly recommend getting the Toyota Dealer Service Manuals. Hunt the various forums.

Haynes and Chilton's are for light maintenance. They are often wrong.
