2007 g35 coupe A/T

Today I tired splicing aftermarket microphone wire into Bose factory microphone(no it didn't work to anyone that want to try). In this process i don't know how but my dome light isn't working nor my power seat on the driver side / passenger side seat only can recline and decline. Any ideas on how to fix?

My steps in troubleshooting didn't work
1. Check fuses in the battery with light n multi meter - good
2. Check fuses box on driver side door - good
3. Thinking I shorted something out on the factory mic, soi disconnect to isolate it - failed

I don't think it's the motor because how was messing with microphone or phone wires on top fry the motor on the seat. Everything works but the power seat. I'm a military member over sea n there is no dealerships that I can take it too.
Any ideas from anyone would be great.

 

Did you check both fuse boxes in the battery compartment? There's two, not just the one up front that's easy to see.

 

No I didn't. I will check on it today. Where is it located at?

 

Behind the battery.
