Anyone have a sure fire location for an EASY to get to 12v switched power source. I am about to install a purge kit to my NOS system, it seems that everything in the fuse box is constant on. So is there a wire I can splice to or a fuse i can tap to get a 12v source that goes cold with the key?
Thanks

 

try the stater solonoid.

 

I can't remember what the number is off the top of my head but this one works for my electric water pump... the one diectly under the tap in the picture below...

 

Thanks!

 

You're welcome!

Update, the one under the tap is # 42 that I used and is "live" when the key is "on".

Fuse # 40 on the other side of the center bolt of the fuse box (fuse with the red wire going over top of it) is "live" only when the engine is running.

Your choice...

 

I know this is an old thread but want to provide proper info cause this post confused me for a second. The fuse with the red wire going on top of it is fuse #43 Alternator.
Fuse #40 is right above fuse #42.
