imoboliser (as10) td5 yr2000 whereabouts

Hi
Have bought a second hand ecu to have remapped it came with the as10 imo green box..remap guy says i should check they are paired (i know they are but will check anyway)

I have read somewhere that the as10 is behind the speakers in the dash, as my defender doesnt have speakers im a bit stumped and dont want to start just pulling the instrument cluster out looking for it.

Any ideas?

If you take the instrument panel out, you will see two boxes mounted down lown on the bulkhead. The green one is your 10AS.

many thanks
Will go and find it
