Which wire is the anti-theft on MB629052 93 3000gt

You can't. It has an anti-theft device. The days of boosting a car with a couple of wires ended in the 1980s! You have to fix the problem, not find a way around it.

hi,

check ign fuse in engine compartment, if blown take the distributor cap off and cut the wire that runs to that capacitor( small silver cylinder}, tape the wires off and put it back together replace fuse and see if it starts.

There is NO way to disable anti-theft. It wouldn't be called anti-theft if you could disable it.

No you cannot by-pass the anti theft system.

bcm has very little to with the anti theft. you need to de active the anit theft

General anti-theft devices are connected with the original car ignition switch wiring harness on the firing line first connected to the anti-theft device, drawing a line of fire from the anti-theft device into the ignition switch. You can the combination switch the first guard removed, and then find the ignition switch, disconnect the two lines you will be connected with the anti-theft device, FireWire directly to the original vehicle wiring harness plug connected to the ignition switch on, you can normally start.

If the security or anti-theft light is flashing when you attempt to start your car, and the engine does not crank or does not start, you have an anti-theft problem. The system may not be recognizing your key's key-less entry signal, or there may be a fault in the anti-theft module or wiring.

Heres the skinny....the wire around the ignition switch is actually an antennea for your anti theft transponder system. the other two wires work in conjuction with the anti theft system in that it supplies power to the ignition switch itself when your key is inserted into the ignition. Inside your key is a chip which emits a certain frequency known only to your vehicle.....when this key is near the ignition switch (ie going to start the car) the antenna senses the frequency and the anti theft system powers down and powers up the ignition so you can start your vehicle. Thanks for using fixya! Any more questions shoot me a email!

Sincerely,

JC

you should be able to use the key to unlock the driver door or the back hatch and that should disable the anti theft.
