alarm still trying photos inside

well i have looked all over for this alarm bx under steering wheel i cannot find anything please help i have getting a new alarm remote off ebay and there is no sticker on the back of it, and when i try to program into car i get nothing thanx frankie heres what i can see also what is this yellow plug for hanging down?

its a weird situation when i take the black plug out photo underneith with wires joined together the car wont start looks like somebody had wired the immobiliser up weird? i put this relay in i got from local scrapyard aadn tryed to program the remote in still no joy the car started with this in but the remote didnt help , looks like i am at the end of the road with it looks like i will have to buy a after market alarm:sad-smiley-047:

Dunno what's happened with that dodgy wiring, but iirc the alarm relay fits in the sockets above the purple central locking relay!

The yellow plug
