I expect LR4 will be the same....

 

Anyone? About to dive in as my new seats just arrived.

 

 

Old thread I know but you were doing the same as what I am doing.
This pic above is the connector from your main cabin harness? Did u just plug it into the new memory seat? Does it all work? Are u missed a black wire?

 

It’s been a whil!e. I did eventually get a wiring diagram. I think this is the car side. I was trying to add memory seats from a Range Rover sport to an LR3 without the memory option. They were newer generation CAN bus. I ended up adding rocker switches and sending 12v to the motors so that I could adjust the seats. It was less than ideal, but I liked having the upgraded seats. Installing the rear seats required spacers, welding, and longer bolts.
