not really sure what answer i am hoping for really, but going to ask anyway referring to this photo: am rebuilding a 205 1.6 gti from scratch. i didn't pay much attention to pulling it apart but did notice it had a few wiring alterations around the ignition barrel area. i assume it's fairly common to see things like this, maybe it'd had some form of alarm etc in the past the car ran fine anyway before i took it apart, and it may still run fine when i come to put it back together (well, with it's gti6 engine) this grey plug which is near the ignition barrel - forget what it connects to exactly until i put everything else back in - it's basically got 5 wires which i need to clarify what they do / what they DID the 2x green ones were always cut and had nothing connected the black wire at the bottom next to the green wire (which has a brown wire crimped to it) went to the +12v side of a red LED bulb (looks like alarm warning light in the dash) both of the other wires are earth wires which are splicing into the above earth to the alarm LED, but they run through a 'push to make' switch, which looks like a tiny contact sensor, something you'd see under the bonnet so when it's lifted it breaks the circuit is this the remnants of an old factory fitted alarm? or aftermarket alarm etc? no alarm disabling or anything was needed when i bought the car to start it or anything. no infrared fobs etc.. just key to start it i've also seen a few chock blocks which look interconnected to pick up feeds from the indicator stalk and these branch over to the ignition barrel loom. so just wondering if this is typical of another alarm being there in the past technically so far i have no problem as the car should still run as before but i'm always curious of stuff like this
