so on top of my 3 security systems, i decided to do a kill switch

i got 16g wire to splice from the fuel pump line and split it into a toggle switch. the toggle switch is 12v. it worked for a bit, but when i slow down, it dies. so what would be causing this.

do i need a higher volt toggle switch...or a relay. also the prong on the toggle switch was very lose. i believe i bent it so much it got very lose.

 

Probably just need a better quality switch. Spend like 10 bucks on a good switch, don't use a 1.99 parts counter switch.

 

^did this

no issues anymore

thank you
