Default fuel cut-off switch question..

still kinda confused after reading many threads..

some mention that u "have" to use a relay.. some say you dont "have"to...

what i understand is that if you use a 25a or higher switch u dont need the relay..


which wire? yello/green or black??

came upon this thread and the guy says wich ever one u want to cut.. so im confused there..

I installed a fuel cutoff switch in my car. It's a yellow/green wire that runs down the drivers door sill and to the fuel pump under the rear seat. First i just put a switch in-line with the yellow/green wire and added extra wire to mount my hidden switch. I ended up blowing the fuel pump fuse like 5 times at random times. It was a bad situation. Finally i removed the extra wiring and put a relay in-line with my yellow/green wire. I ran the extra line to my switch. It's worked 100% since then and i've never had anymore blown fuses. I highly recommend using a relay cause it's only like $6 and you can hide everything better that way.

Here's the most awesome honda/acura security site you'll ever see. It was put together be a guy that's on the forums. It has wire color maps, detailed pictures, and he gives excellent pointers and tips about how to make a car virtually impossible to steal. It has a menu in the upper right to find all the good stuff. Check it out.

Can't remember what wire to use, but a generic toggle/rocker switch will work.... side note- definitely do this, someone attempted to steal my hatch a long time ago and they only got it about 25 feet with the gas in the lines. The switch saved my car and lots of hassle.

yes, the main relay is what I wired off of. It's one that usually craps out during the summer on Hondas.
