Cruise on a ZT-T

[Morrisfan]

I'd like to fit cruise control on my diesel ZT-T, is it a practical diy upgrade? is there much wiring/dismantling involved or is it (I wish) just a matter of adding switches, black box etc?
If it is a practical proposition could someone tell me what parts I'd need to buy to complete the upgrade?
Thanks.
Neil.

Pop the lower dash switch panel off, if you're luck the wiring should be there, (it'll be a blue or black plug, one is traction control the other is cruise, can't remember which is which off hand)

If the plug is there you need an ECU, dash switch and steering wheel switches. About £100 in total.
