the lantis challange

hey guys,i'm trying to get my dad crazy by "making some changes"in his vehicle(which he cares about very much and hate making changes in it). i was thinking doing it by making the doors lock on him when he turns the ignition on and open when he turns it off. now here is the deal:i have two wires one GREEN/ red for lock and one WHITE/ red for unlock. both of them are activated by a neg pulse(no resistors needed)now the first part is to make a relay that turns the ignitions + to - but the problem begins here:i need an electricity genuis(and there is lots of them in this great site)to help me think of a circuit as follows: ignition on-->neg PULSE to GREEN/ red wire. ignition off-->neg PULSE to WHITE/ red wire. please help me create this circuit cause the "what da f***?"face of my dad after i'll to this worth it all... thanks rami. by the way,of course i'll deny any connection to this "problem" what will make him just mad...

I will go ahead and be the first to say don't **** with your parent's cars. You can cause damage if you don't do it correctly. A better trick is to tie his brakes to the horn or turn signals to the horn.Certified Security Specialist

Always check info with a digital multimeter.

I promise to be good.

Tell Darwin I sent you.

I've been sick lately, sorry I won't be on much.

i just wanna annoy him not cause him a heart attack (tie his brakes to the horn or turn signals to the horn)

stang351w,as i said it's a lantis(protege)in the u.s and i dont see how locking and unlocking the doors will fry the ignithion...

i didn't mean  just locking or unlocking the doors would, what i meant is where you sugested useing a relay to switch the + from the ignition into a - pulse for the locks. you've gotta tap into the ignition wires if you take that route and that's where the potential for ignition damage could happen. i'm not sure excatly what relay setup would be needed all i know is it wouldn't be easy, switching a (+) to a (-) isn't so bad..but you need a neg pulse after you get it to a negative. alot of wires, a number of relays, increased change of damage.  that's all i was getting atTri County KustomZ

wow! that complicated?how many relays are we talking about here?and there isnt a way to convert steady - to a pulse -?

buy a tr7 pac adapter for $20 call it a day

what is it?

http://www.pac-audio.com/instructions/tr7bonus.pdf feature 19 is what you want, its a programable relay, with a ton of different functions. feature 19, lets you program it to send a negative pulse (lock the doors) when the ignition is applied, and when it doesnt see the ignition signal, a neg pulse(unlock) will be sent. :) easy as that
