96 hatch, putting push button start in. Going to get the crimp splices for the constant and ignition wires, but going to cut the start wire so the key won't start the car anymore. Anyways, just wondering where or if I need to add a inline fuse. Not sure where the fuse needs to be in accordance to the relay and push button, since I am adding another load in the circuit (the led light button). Thanks for the advice, just don't want to be frying any circuits without a circuit protector. I would greatly appreciate the advice.

 

I would just put one In between the push button and the ignition wires. Because the Ignition wires them self are already fused

 

Makes sense for the ignition and constant 12v wires, so that if something goes bad with the push button it would pop the fuse before reaching to the splice into the regular harness. What about the with the starter wire since I am actually cutting it and splicing? That particular circuit amperage is partially the amps coming from the ignition switch, so since the push button is replacing that is that what you mean by it already being fused? Might i need to compensate if the push button and original ignition switch's amperage ratings are differet? Thanks again just trying to clariy.

 

all the wires leading up to your ingnition switch are already protected by a fuse in the fuse box so the only fuse you need is inbetween the pus button and the Ignition wires.. if I were you I would just use the push button to trigger a relay witch inturn would start your car enstead of having all that amperage running through your push button.. and you can conseal the relay so that way somone cant just pop out your pushbuttion and cross the wires and start your car... but thats just what I would do.

 

thats what i plan on doing, the push button has a relay on the back which is wired to ignition wire, constant, and the starter wire. so what amp fuse should i get, 40 amp for the 40 amp starting circuit or just the required amperage for the button?

 

if you have it running through a realy you wont need a 40amp fuse.. I would just throw a 10-20amp fuse in there and call it a day.. what do you mean there is a relay on the back of the switch that doesnt make any sense?

 

Sorry worded that wrong, a relay comes with the switch and is located down stream behind it. That makes sense with the relay not needing as high fuse rating. Lastly, since there are 2 ignition wires hooked up to original ign switch, but olny one coming from the relay of the push button do I need to split that into two so I can crimp/splice into ign 1 and ign 2 wires

 

You wanna wire it like this..



Here is a write up on an S2000 Push start this should help you..
