I just did this, my car is a 2011 and the seats were 2009. The wiring diagrams kind of helped but here's what I did:

Passenger side very easy
I used one of these to connect the two wires 7 and 9 on the seat side


Driver side
Same deal but you have to bridge the plus side and the ground
So two of those connectors, red and black wire with the red and brown. Then brown with brown.

I managed to take a few pictures of the drivers side wiring:

Ok I’m about to tackle this. Are you saying they don’t need to be repinned at all? They just need a jumper to connect the wires together? Essentially connecting them together so that power is now shared between both wires?

Finally found this thread... really helpful

All is working. I am not yet completely happy with the splice material used that links the wires together, so I might redo it if I can find a better split joint.

your report really helped me.
All this time I thought that the problem in the side bolster motor or its module.
Already try switching parts between left and right seat but all parts seems good.

After reading your post, finally I check the connector and understand that pin no.7 and 9 from the car are empty.

Following your steps, now all runs well...

Thank you sooooooo much for this post! I have an LCI with heat + power base seats, got LCI sports ones and naively figured it was plug and play. Look around and see everyone talking about repinning connectors and such which is well beyond my comfort zone (am comfortable mechanically, not so with electric stuff). Pretty confused about what to do.

Of course the seats came with lumbar maxed out, literally felt like a basketball was wedged behind me. Came across your post...never seen those connectors but easily found locally. Your directions made sense, pics were super helpful. Verified wiring diagrams so I'm not just following stuff blindly. Still makes sense. Proceed with splicing and BAM! All works perfectly, no more basketball, seats comfy af. Really appreciate it!

Allow me to second the massive appreciation for your post. After, truly, hours of research over many days, with very mixed information resulting, this was exactly the solution I needed.

My situation, in case it helps any others:

My car: 2011 LCI E91. Standard seats w/ power, heat, memory.
Donor: 2009 LCI E90. Sport seats w/ power, heat, memory, bolster (no lumbar).

Solution: exactly as E86Z described:

Passenger side - bridge 7 & 9. I had contacts on both, but only on the passenger side. The bridge connector was able to fit inside the back of the yellow housing when I reassembled.

Driver's side - bridge both red wires and both brown wires. Which I believe is 4&7 and 8&13. I didn't have contacts on 7&9 on drivers side, hence the different process.

Luckily Cambodian Tire sells 3 packs of bridge connectors, which worked out perfect: https://www.canadiantire.ca/en/pdp/motomaster-22-18-awg-self-stripping-tap-connector-3-pk-0206928p.0206928.html

Again, huge thanks to E86Z. Hopefully this information helps the next victim trying to sort this out.

I’m going to give this a try tomorrow and hopefully it works, just had the motor out of the back and swapped it over with my E82 one to see if it was that but it wasn’t, onto the harness now
