i recently installed a cutoff switch..i used 18 gauge wire and i believe 6amp rocker switch..i read that 18ga was okay but can someone confirm that? i believe i read somewhere it fried on someones car while driving at high speeds..also this past week i noticed after installing the switch the performance has gone down a bit..could it be that the wire is not big enough because as i step on the gas it doesnt react as quick.feels like it takes a sec before fuel gets to the engine..last quewstion is anyone know what wire to cut to disable power locks..thanks

 

Well, increased resistance could, I guess, cause that... how did you join the wires and the switch together? I hope you soldered it?

 

yea the connections where soldered and wrapped in electrical tape..so 18ga is okay?

 

Electrical signals travel at the speed of light, even if it did have some resitance, you would never notice a lag...

 

Resistance definitely would be an issue. I take it this cutoff switch was installed on the power wire for the fuel pump? If the pump is not receiving enough current it can indeed not perform like it's supposed to. 18 ga is some pretty scrawny wire.

 

im not sure which wire its considered but the yellow with green strip with silver dot wilre that runs along the left side of the car from the back seat was jus cut and tapped into..is that the power wire?

 

Nothing travels at the speed of light unless it can move in a complete vacuum. The lag perceived could be from the fuel pump not receiving enough of a signal from the increased resistance.

 

BTW, your Integra is a DC, I take it? Just curious.

The wire seems too small, I'd go to 14 gauge. Also, instead of a direct switch, I'd use a relay to switch the current to the fuel pump. It should be fairly simple to mount the relay under the center console bin :dunno:

 

But what would be a good thing to hook the relay up to? It's gotta be something you want on when you're driving the car, but a thief wouldn't turn on.

Relays work great for starter kills, but are less convenient for fuel cutoffs.

 

I was considering the option of installing a relay as a more secure means of switching a high amperage circuit w minimal resistance. The relay would be controlled by a low voltage circuit added to the car, with the switch controlling the relay hidden inside some storage compartment or under a false panel.

I'll come back to discuss this a bit more clearly in a bit, hopefully.h:
