Gday I have to insert a relay to immobilise my Z as a part of my alarm system. Obviously it will be triggered by the alarm. Just wondering the best place to put it as the alarm diagram does't really specify where to put it. Did a search but everytime the answer is given via P.M being a security question so searching is fairly useless on this topic If you could quote why you think it is the best place, it would also be helpful - i.e. they will never find it here / or this spot actually disables it in three places etc Regards JC
Sorry - no words of wisdom here, just a polite request... Please send answers to Jamie via PM so the answer on how to break into our cars isn't here on the interwebs for eternity.
Well they will find it there if they have access to the internet...this thread will tell them. There is a reason why past security Qs have been answered by PM, no?
hey buddy, if your not confident in what your doing you should get someone who does to do it for you, having said that, immobilizers generally go on ign relay, fuel pump relay, and ECU relay.. where along the wiring they get spliced in should differ for every car to make bypassing difficult.. with the zed, its awesome and crap that those wires do laps all over the car for fun, so you can pretty much tap into them anywhere immobilizers don't stop thieves as they're very easy to find and bypass half decent immobilizer should have three points of immobilization, not one
Same rules for any car. Stop it cranking (ignition switch), stop the fuel (fuel pump), and stop the ignition (ECU, coil power). If you're keen, add an alarm and a completely separate immobiliser (ie wire it up to separate spots) and make sure they are both passive arming, with auto central locking. There are some pretty good proximity immobilisers available, which require a passive key 'fob' (just looks like a plastic disc) to be placed adjacent to an inductive pickup before the immobiliser will disarm. The inductive pickup can be placed inside the steering column with the fob on the keyring, or you can place the pickup somewhere else, and put the fob near it to start the car. I also have a low tech backup, which I think works well. In addition to fitting alarms and immobilisers, get some chain and two locks. Loop one end through the steering wheel and lock it, and loop the other end around the brake (and clutch if a manual) pedal, and lock it.
Dangerous said it all. Three points of immobilization will cause time and complexity and that's not a car thief's friend at all. A few little tips though; make sure your immobilizer has all black wiring, make sure alarm siren has a backup battery, tape up all wiring where you slice into ign, starter and fuel systems with black tape to make everything look factory and a little flashing LEDs mounted on dash can assist greatly with giving warning that security is in place. Remember, having the most immobilization points and sophisticated location of immobilization points is not a complete safe guard towards theft. if the thief really wants your car, it'll be on a tow truck. If you need info on factory z32 wires to splice into for the install and other great tips, use the12volt.com vehicle database which has assisted me greatly, but a multimeter also works fine.
Installed two of these bad boys (Zed and WRX) and it has been great value for money. Installation is not difficult (having absolutely no experience before hand - just sound systems) it only took me a few hours.
