the person who i bought the crx from had the fuel pump wired on a switch. So today when i was driving the fuel pump shut off, come to find out the inside of the switch broke. so i went to the store and bought a new switch, their are only 2 wires thatcome off the switch. A ground and power wire, do i just reconnect the wires? i noticed their was a 3rd wire but not sure where it goes on the switch being their are only a ground and power wire outlet on the switch. will the switch burn up if not wired correctly? im not sure where that 3rd wire went to. I drove the car with the new switch hooked and drives fine, just wondering if its installed right.

 

find out where the 3rd wire went, but it sounds like the switch is in a power wire and is sending power from one source to 2 different locations when in the on position

FYI - switches do not have a power and a ground - a switch is just an interrupt in the wire - if a switch is installed in a power line, the switch in the on position allows power to flow thru - in the off position, no power flows thru - same if installed in a ground wire, the switch in the on position allows the ground to be completed - in the off position, no ground - a typical example of a switch in the ground wire is the cooling fan switch - when temperature gets up to where the switch closes and which is the same as turning it on, the ground is completed and the fan turns on - if you connect power to one side of switch and ground to the other, when you turn it on you run power direct to ground, otherwise known as a dead short which will blow fuses, discharge battery or burn up the wiring

 

im not sure if it even went to anything, the wire wasnt even spliced like the other two were. when the switch broke i just twisted the two wires together so the fuel pump would work so i could get to the part store.

So i guess the switch does the samething as twisting and untwisting the wires together? the fuel pump has been wired this way for well over two years and never had any problems.

 

There's a how to on this that will help you in the faq

 

yea i read it after i posted this.

 

i had the same exact switch and thats the one that busted. The new one i bought was already prewired and all i had to do was solder the wires together. I guess that 3rd wire is there to just throw me off. Although the wire that was used was speaker wire and you know how each wire is like a double wire, and they only used a single piece of the double wire and left one hanging next to it to throw me off....bastards.
