I'm wiring up my s2k engine start button and I need someone's help finding a good 12V power source that activates when I turn the key to the start position.

My mind is running a blank right now so any help would be appreciated... TIA!

 

catch it off of the main relay. or look in the fuse box for an ign 12v. there should be 2 pins there hot with the ign on.

 

the radio has a switched source

(Yellow/Red)

DON'T use the radio power. Every time you push the button, your going to draw more current than the radio is fused for, thus blowing the fuse and you car won't start at all. Take off the drivers side under dash. If you follow the wires to the ignition column, find the thick black wire with a yellow trace. Thats your switched 12v wire. All your ignition wires are covered in plastic, just use something to cut the plastic away. You'll know its the switched power wire because it will be mixed in with the other ignition wires (yellow, white, black/white). Make sure you use a fuse on it just to be safe. I wouldn't use any other power source for an ignition related item....

 

to give a bit more info in case you need it...
White is constant 12v
black/white is your starter wire
black/yellow is ignition
yellow is accessory (drops during crank)
white/black is 2nd accessory

 

alright awesome help, so I should tap into the black/yellow wire comming from my ignition correct?

 

back up for my question

 

come back

if you splice into it directly than yes you'll suck a good amount of power and blow the fuse.

When you're doing the s2000 button conversion you should have a relay and a seperate fuse line.

 

Are you installing a aftermarket start button or an OEM S2000 Button?
