sorry guys.....I didnt search, i cant right now, so please please please can some one please answer my question,......

- is it safe to use a 25 amp 12v toggle with 14 guage wire to make a kill switch using the main engine harness.

-hack the red ignition wire and run in into the car?

not for my car, friend almost fell victim to the shmuck of the world...


thanx lots

Yes you could, but why?
It would be more effective to install a switch on the ground to the PGM-FI Main Relay, it is a low current ground, [a 1A switch is more then big enough and a lot easier to hide] and it will shut down the fuel pump, the injectors, one of the powers to the ECU/ECM and a few engine sensors. ; 94

 

thanx man, im gonna look into your idea... thanx again

 

and don't just kill the main relay, relocate it.

Do you know of a DIY with pictures for doing this? I know there are some flagged DIYs but I want to do something in addition to fuel pump kill switch, or is this the same thing? All this security gets me confused. I have a headache.

 

Installing a switch on the ground to the PGM-FI Main Relay, [ground to fuel injector relays coil] will cut power to the fuel injectors, the fuel pump, one of the powers to the ECU/ECM and a few engine sensors, [the ground is a black lead, it is low current, less then 250mA].

Where is the ground wire? Is this as simple as doing a fuel pump kill switch?

 

What car do you have? On many older hondas its located right above the hood release, its a big relay, nothing like the small ones used for the k-series. If I remember right there's only one ground wire, its a great kill, have done it to nearly all the older hondas I've worked on.

You don't want to run over a raccoon and have its bloody carcass switch off your fuel pump. You'll be in trouble when his raccoon family catches up to you and avenges his death.</TD></TR></TABLE>

That's some sick and twisted **** to say. I laughed, then I immediately felt guilty. Karma's a bitch.

 

lmao thats what suspended hatch said once, for some reason it gave me a good laugh.

</TD></TR></TABLE> Even simpler, as it is a low current ground, [less then 250mA] instead of a "high current" 12V+, [10A] so all that is needed is a small, [easy to hide] 1A SPST, [on/off] switch, this may help... http://www.tegger.com/hondafaq/mainrelay.html

 

So you just put an extension on the ground from the relay and a spst wherever you want? (within reason)

What gauge is the ground wire? And it's black?

 

wow thats a good idea (much better then the same old fuel kill switch), 1 more layer of security to add

 

Yes it is black and it will be 18/16 gauge. 94
