Electric seat wiring help

[dulux72]

I've recently changed my seats and am trying to complete the wiring of all the functions
I have purchased a pre made loom for the heated seats and successfully added into the fuse box etc.

However when I got to plugging the seats in I am confronted with this
The seat has 3 plugs (1yellow, 1 red and 1 black)

The seats I removed have 3 plugs (1yellow, 1 red and 1 GREEN)

The sockets supplied with the loom look like they would fit the old seats but not the new
Doesn't anyone know what the black plug is for and have a wiring diagram so that I can reconfigure ?

Hi,

What car did you the new seats from - and did are you moving from manual to electric seats, no heating to heated etc - please give full details of the before and after functions?

I assume you are installing them into the 2.4 Cab - I did this several years back in my 2.4 cab, moved from manual, non heated seats to full electric heated with memory function.
