Is that a thing? I know the MOST Bus will stop working if 1 thing is not operating. I did not know the same can be said about the can bus. Either way I'm going to try it tomorrow. I also want to check voltage at the seats bus wires and see if theres any life there... I have so far only checked voltage is definately present.
I spent today replacing the footwell module (i probably could have just reset the short circuit counter but the FRM in donor car was a FRM2 so free upgrade.. AND i replaced the JBE module to rule that out. Turned out to be a good idea... i found a bit of corrosion on like 3 pins in one corner..
I now have footwell lights.. still no side view mirror.. Haven't re-read the error codes again so far to see whats left. I just desperately need my seat to work.. and at this point I'm pretty convinced those can wires are not doing what they're meant to..

On a side note.. if you ctuna or anyone else following along knows where exactly the factory drivers seat wiring runs along.. Would save me a bunch of time..
Else I'm going to rip carpet from the donor car (theres no dash anyway since i already pinched that for mine) and manually trace it through and find out what i've broken.

Anyone else reading this that's about to do a retrofit.. for dash/headlights/radio.. whatever.. take my advice.. dont mess about and just transfer EVERYTHING if you can.. Would have saved me a bunch of trouble.
