2000 Civic Si Master Switch

[Chip42]

on our hondas, including a '99 Si (same as your 2000) we always replaced the stock cable from the battery to the starter and main fuse box with a new cable to a switch mounted inside by the left wing mirror. Return cable to the starter then up to the fuse box in the stock location.

Cut the IG1 line from the key switch and run it through the smaller NO contacts on the switch. this will kill the car and not create an alternator issue. and it's easy.

Thanks chip. I thought it looked like it should be that simple, but I appreciate the first hand info. Really wanted to avoid doing unintended damage. Just to clarify, the contacts the IG1 goes through are closed when the Master Switch is ON , and open when it is off. Correct?
