Hi, so my car has trouble starting, it starts but then dies as soon as i let go of the key. I took apart the plastic surrounding the ignition to see if there was a a loose wire or something . It turns out i was right there is a loose wire coming from this yellow box thingy . Can anyone tell me what it does ? As i have replaced with a 2nd hand one from a wrecked fto and soldered the wires together but the car still won't start and when i turn the key to on the dashlights flash for a second and go off and they dont come back on unless i leave the keys out of the ignition for like 3 mins and put them back in but the same thing happens.

OK, thats just part of the wiring for the ignition barrel I think. That wont be your problem. Its much more likely going to be the things mentioned in the other thread.

Pretty sure that's the thing that beeps when door is open and key is in
