HOW TO FIT leather heated seats and electric lumber support

[letsgetrdy]

Hi guys, replaced my seats today in my 11 plate, with seats from 14 plate, drivers is heated etc with electric lumbar, passengers just heated. Passenger one fitted fine but my drivers seat connector is totally different, can anyone point me in the right direction? Will I have to entirely unpin the connector then either use old connector housing or just spice them in one by one? 

Here's a photo of the drivers side connector. Passengers was same as old seats and no Probs!

Thanks for your reply, ignore my snip job but I done it temporary, tomorrow I will solder and seal. https://www.dropbox.com/s/93oxcd7d212mdr...4.jpg?dl=0

I used the old connector from old front seat and then just wired up every wire it had (very few). Car side I'm good to go I have every pin there, just trying to work out what to do with two mysterious wires, namely a smaller red one and a second grey / black cable but with a bigger amount of black so I'm guessing BK/GY, but can't find any mention of it.

This is what I'm down to - https://prnt.sc/ky68fx

I've been referencing this from this forum - https://www.vxoc.org.uk/Images/vxoc%20as...arness.jpg

Any help on what the last red and bk/gy could be would be appreciated.
