Stealth security: fuel pump kill switch (6th gen)
I'm researching doing this simple security mod: a fuel pump kill switch for the 6th gen civic.
My motivation:
- added security against casual thieves (I'm assuming if it's a professional thief, there's not much I can do)
- although easy to defeat, I'm assuming it's not worth the theif's time to debug the problem
- cheap and easy mod
The design:
I'm looking at the service manual and it looks like the fuel pump gets a yellow/green wire from the ECU as switched power for the fuel pump. The fuel pump, which is over the fuel tank under the rear seat, uses its own ground, so there is no ground wire from the ECU. I'm thinking about getting an appropriately amperage rated switch from RadioShack to interrupt the 12v switch power supply to the fuel pump. I would like this switch to be hidden (duh...) from plain view, but easily accessed by the driver, IF you know where is.
Does anyone know the map of where this yellow/green wire runs from the ECU passenger kick panel to the fuel pump? My friend's accord happen to go through the center so he hid the switch just inside the ebrake housing (reach a finger into the base of the ebrake and flip the switch).
(searches come up with lots of ignition kill switches, not what I'm looking for.)

easy as pie!
why did i use that title...anyways its extremly easy, dont even deal with wehre it conencts ot the ecu, pull up the back seat, splice the wire, and run your switch where ever you want underneath the carpet. Ive had mine in for 6 months ever since the bastards stole my 2000 ebp stock mint si and left me with just a shell. Hurry and get the fluel pump swtich as soon as you can, and you better have at least the stock alarm system. You can get one from slhondaparts.com for about $30, which also gives you a starter kill. I put my fuel pump switch in the trunk and locked the truck so that the pull from the inside doesnt work, you have to use a key. I also put my faceplate in my truck so they cant just open the glove box and take my ENTIRE ac/headunit bezel. I also use the CLUB lol so classic.
