Wiring 4 post cut off switch for ls1
 

Anyone have a diagram or can explain how to wire a 4 post terminal cut off switch for a ls1? Pretty much stock components/accessories.

Thanks!

I was told the positive side of the battery connects to the on side of the switch (1/0gauge).
Negative side of the battery grounds to frame (2gauge).
Off side of the switch connects to a junction block (1/0gauge) and that connects the fuse block, starter and alternator (factory cables).
And I'm not sure what the two smaller posts are for.

In layman terms or a diagram would help. Thanks!

I put an answer to your question on the Bullet. For those here that don't go there, the large pair of posts are for the positive cable. For anyone running EFI, use the small pair of posts to kill the fuel pump relay. Works perfect! Been wiring EFI cars that way since 1990.
