Pre-LCI seats in LCI car? (Active Headrest)

Hello everyone.

Installed pre-LCI seats (2009) on a 2013 E92 M3. The seats did not have Active Headrest connections, which is why I suspect the airbag and seatbelt lights are on.

Is it possible to code out the AHR to clear the lights?

Yes it can be coded out

What needs to be done to code out the active head restraint?

Which ECU and which value?

I don't think the errors can be coded out. I've coded out every error that pops up as a result of a similar seat swap and the errors persist. I think the connector needs to be jumped with a 1.8-ohm resistor, which is what I'm trying next. I'll report back.
