delay for turbo timer?premade units?

ive seen a few people post the diagrams for making a delay for turbo timer with aftermarket alarm. i work at the shop and deal with it alot some alarms come with timer option but most cheaper ones dont i tried the relay on one of the alarms but it still triggers the shock sensor when car engine spins down after shutdown. does anyone make a plug and play units that i can use instead of making it every time?

or maybe a simplest possible delay of 1 sec? i have looked thru the forums and alot of replies are with broken images so they re no use.. i found a 555 timer IC that looks like it can be used
