120 Factory Alarm... Hmmm What Alarm!

Well you've picked a bloody complex alarm there mate! It is capable of so much more than of being an alarm and remote start also. mine can switch on my spotlights, work light and fire up my radio independant of accessories whenever I want and from outside the car. I have even hooked it up to winches to feed cable in or out. When I'm out camping out can start my engine f it detects my voltage is too low. If i remote start on cold mornings it will sail on my rear demister and heated seats. In my wife's mercedes it can automatically switch the heater to max or I can make it go minimum cold AC. But.... you need a really solid understanding of electronics. On a diesel you can make it wait for the glow plug light to go out before it cranks also.

I'm happy to help you out and if you live in/near Melbourne I'm happy for you to bring your truck to the workshop and help you t hat way (no charge). First off though.. throw away that piece of wire and your test light. Get a multimeter or a super duper LED test light. I have one made by Jaycar and it is the best damn tool I ever own. I often find it more useful than my $900 multimeter! You will also need to understand how a diode works... google "the12volt.com blocking diodes" and it'll be the first page and also get yourself pretty handy with relays. The Viper MUST be soldered into place. No crimp connectors or twisting and taping. Solder and quality insulation tape are a must. I prefer Nitto tape but so long as it is good quality and not cheap crap... You'll be fine.

For the remote start you'll need either a DEI PKALL or a 556U immobilizer bypass and a spare key to sacrifice to the install or get a locksmith to clone you a copy of your transponder without the actual key. The alarm will work without it but the remote start won't. The most reliable of the two methods is the 556U and transponder. Th pkall must be programmed and if you screw it up... the units toast as it can only be learnt once.

I will PM you my phone number and give me a call.

P.s. the lock wires are accidentally reversed in the list but it doesn't matter for you as they are only for an upgrade alarm... you have another two wires to find.

Hi Ranj,

Thanks for that , greatly appreciated. Still having a couple of dramas... test for STARTER and found TWO positive wires... one was black/white and the other was green... so I cut the black/white and wired the green from the viper to one end and the purple to the other... but when I arm the alarm, I can still crank the engine with the key and it starts ?

So now I am guessing that I should have cut the green wire and did it to that instead? Guess I am soldering the two ends of the black/white back together and trying again. Don't think I am going to bother with the remote start as it won't work anyway because of the transponder in the key I am guessing so unless I can get a Prado bypass module to do that I will just leave it. Can't believe how little info there is on installing an alarm into a prado which is a very popular vehicle.

I work in radio and also do karaokes and leave $8k plus worth of gear in the car sometimes so need the alarm to page me if the car is being broken into.

I live on Central Coast NSW and work in Newcastle mostly. My number is 0409 240660 and I would love it if I could have a quick chat before I going chopping away at the car tomorrow afternoon LOL

Thanks heaps,
Dean

ps: yes I too love all those 200ma auxiliary wires in the alarm... was thinking about wiring the sunroof into it and maybe the light bar...
