Disconnect IPK wiring loom - how?

[ianM]

Hi all,

Just hoping someone may be able to give me a hand on a drizzly Sunday. I'm trying to get my instrument panel out, and I've hit a snag with disconnecting the wiring looms from the back of the pack, as I can't figure out quite how the clips work. I'm sure there's a knack to it, but I just thought I should ask rather than stamping on ahead and wrecking it in the process

Thanks!
