Electric Problems with my s 500
Got a nice S 500 4 Matic
Honestly i though i was pretty good with these cars until i started buying them in auctions
This is my current situation
Car was running great when i bought it changed the air ride compressor and some hoses no big deal
Had some messages on dash
Fail safe mode srs some light werent working
So i tried to fix the light bulbs by replacing them and blinkers stopped working completely along with some other lights in the rear
I found about 30 codes in the rear sam module so i replaced it with a used one but in the process the live red wire in the sam module touched the frame and burnt something
Now i sent it to a freind he got it running again but i still have the same problems rear turn signals not working fail safe mode srs warning
check engine and abs light are now on as well got one code rear left speed sensor the speed sensor i know i can fix but how will i get the blinkers working and get rid of the fail safe messages ?
currently same old sam module still in the car i have the other one in my posession as well i was working on these cars for about 3 years then decided to buy and sell them and now i just want to get this one fixed register it and go back to my mechanic work any help tips suggestions on how to get this s 500 right ? car is in good shape and has all the goodies thanks in advance

You need all the parts that are typically replaced in a water damage event - Get a complete wiring harness and Sam from a donor car , take out the seats and run the new wiring under the floor and in the trunk

Thank you boss you always know your stuff all or a sudden turn signals are working again ? all the lights are working except left tail lights something actually missing from rear trunk lid some kind of module missing ? few loose wires there and i believe VSS will fix fail safe and srs ?
