Q: peugeot 205 1994 ignition barrel with key needs replacement do any of peugeot's latest model replacing 205 have the same ignition system would it fit to 1994 diesel?
A: The 1994 ignition barrel from a 205 has 6 wires on a plastic pin connector. Coincidently, SO DOES THE 306. I have extras of both out in my garage. I will now immediately check for Pin connector match? and the outside diameter of both. It must fit inside the black metal tube in the steering column, that surrounds it. THE SIMILARITIES: Both barrels are 34 mm in diameter. It will physically fit. Both of my examples are from PETROL CARS! THE DIFFERENCES: ....THE 205 has 4 heavy wires. Green, Yellow, Red, Orange. after 12 inches, the Red and Green divide into two smaller gauge wires. Now you have 6 wires. Both red wires end in a 4 pin, brown connector in positions 1 and 4. The heavy Yellow, Orange Green and Green end in an identical size connector, but white, in positions 4,3,2,1 respectively. Total length of the wires is about 30 inches. important under the dash! ....MY 306 barrell is from a 1994, Phase One 306, with only 13 fuses in the fusebox, and a simplified electric layout. It has 6 heavy wires immediately from the barrel. They are all only about 10 inches long! (too short for your 205??) They are grouped in pairs, and the 3 plastic connectors are totally different in size and shape from the 205. MY DOUBTS: The 205 never had an ECU (electronic control unit) in 1994. The 306 Phase Two probably had one after May,1997. Not sure about Phase One 1993- May 97. So, when you turn your 306 ignition key to position 1....what happens? I don't know! I was wrong about schematics...I don't have anything for diesels that shows the glow plugs warming up in key position1. sorry. MY experience. I had to buy an ignition barrel several years ago. 80 euro? = 64 quid? And it fit perfectly, and I had NO connectors to change. I'm afraid I must suggest you buy a new one, OR get an old one off the same type car. Less work, and you're sure. (you absolutely need the key to remove the old barrel from a wrecked car) THANKS FOR YOUR E-MAIL. It's nice to know you can do auto wiring jobs yourself!!!
