I'm trying to cut power to the spark plugs on the 3.6 pentastar while the motor is running (don't ask why . If i get this figured out i will show what it does.). I know fuse F70 is for the Plugs but it also is for the Injectors too which i don't want to cut power to. I want the coils wired up to a momentary switch so when i push it it cuts power, which i already have a switch for. Thank You.

uhm... it is going to be quite difficult to isolate power to the ignition coils as they have that common ignition coil / injector Fuse F70 .. damn.. unless you disassemble the harness and individually isolate each coil with separate switches I don't see any other way to do it ... is this a semi-permanent modification ?.. if so.. I would suggest you go with individual switches... because with a common switch if anything happens to that switch then you will kill power to the engine... imagine if that happens to you on the highway !

Individual relays controlled by 1 switch. You could use a normally open momentary push button switch and normally closed relays so that they are only off while you hold it in the button. Then when you hit the button it puts power to the relays to open the connection

Exactly what I want to do, just need to figure out how. The relay in the fuse box? If so which one. Thanks
