NEED help guys,

I have a 2007 G35x sedan without the GPS features, I've purchased off this seller a complete kit OEM GPS , when trying to install coming to the middle section where there's the radio button / ventilation control .... When plug one of the plugs smoke started to come from the behind circuit board and I immediately unplugged it,

⬆ i circled in red the part that started smoking when putting one of the plugs ( this is the complete kit OEM with GPS feature)


so because of this situation I stopped and put back my original pieces , when I was all done I noticed some of these issues that wasn't there before doing this swap and issues are :
1-yellow light key remains on cluster ( but engine still starts)
2-no instrument on cluster works rpm / speedometer or other lights like check engine / air bag etc....
3- don't hear the relay releasing the shifter arm (automatic) when car is started , need to press the shift lock ..and yes my brake lights works
4- the center cluster messages in red wasn't working and noticed that the 10 amp fuse was blown and replaced and the messenger center in red came back on.

I've checked all my fuses and they are all good

Can someone help me with this issue its driving me crazy

Is it possible that I've maybe shorted the BCM module ?

Thanks


⬆ this is while engine is turned on , without the fuse replaced for the red center messenger

 

When you say "all my fuses are good" you checked the cabin Fuse Block - J/B, the engine bay IPDM block, AND the fusible link on the battery terminal?

I'm betting you didn't check everything and have a fuse blown. Start with the fusible link.

Also sounds like you're working on your computer with the power still on, ALWAYS disconnect the battery before you go plugging/unplugging stuff...

 

Yes i did check and the hidden one beside the battery also and a bunch of them are all good ( not blown) but no power by testing with test light, also checked the link on the positive cable from under and top through the glass and none of them is cracked or blown, the power was off but i didnt unplug the batery for the simple reason
of being scrared while plugging the units and while i was plugging that one it started to smoke up and i unplugged right away ...but i guess the damage was quicker then me
