Help with T flip flop and Power Mosfet for Car switch

[riazhaniff]

Hello

I am trying to control a 12V accessory in my car via a remote switch (the aux button on my car alarm)

I figured one way to do it would be to use a T flip flop and a power mosfet, but im not quite sure how to design the circuit.

i have the SN74LS107AN IC and the FDP6030BL Power Mosfet (over rated) and my signal from the AUX pulse is 12V 1.2 A


I tried using a Relay at first but my AUX signal only sends a single 1 second pulse so the accessory only stays on for a second and then turns off!

any help would be greatly appreciated!
