Hello everyone, new member here. I've been using this forum a bunch for my 2013 and 2015 Honda Fits. I recently purchased my 2015 EX. It has a previously salvaged title from a passenger front end collision. I started with 8 airbag trouble codes and now I am left with 5. I need some help.

Here are my codes:

B0072: Passenger Airbag Pretensioner circuit malfunction.
B0011: Decreased resistance in the passenger airbag second inflator.
B0010: Issue in passenger airbag inflator
B0070: Driver airbag pretensioner circuit malfunction
B0079: ?

B0070: I have two broken connectors which is probably causing this issue. I need to find a couple connectors somewhere.

As for the passenger codes, the passenger airbag pretensioner was unplugged. I plugged it in and got rid of one of the original 8 codes.
​​​​​​Passenger airbag seems to be intact and undeployed. All connectors are connected and I cannot see any visible signs of issue.
The passenger curtain airbag is also intact and undeployed. Although there is a little bit of rust forming where the connector plugs in.

Can anybody please help me? I am unfamiliar with airbags and I'm tired of seeing the airbag light.
