Sorry if there was a thread on this but I didn't seem to find one. Here is a bit of history on my truck, its a 2007 Chevy Silverado 1500 Classic 4WD Z71, I bought the truck and it was stolen before, the seats originally were electric and when the owner found it he put manual seats to replace the missing electric seats. The issue I am having is I have the air bag light and it states something is wrong with the airbag, I would like to clear this out and when searching for the issue in the truck I saw this (see pictures). I'm thinking this the issue, basically the computer is not reading the airbag wires from the seat . Harnesses also don't fit with each other.
If anyone can help I would appreciate it!
