You say you "cut the connector off and connected the two wires directly."
I am not clear what was done ..... did you cut the whole connector off(both sides) and then connect the two wires from seat together and two wires from the floor together, or did you cut the connector out (both sides) and connected the wires together in the same path the connector provided?
I guess what is throwing me is the "two wires" since my thought is there are four wires - a pair from the seat and a pair from the harness on the floor connected through the male and female connector housing.
Anyways - The circuit runs through a pyro device attached via a short thick cable to the seat belt buckle (inboard part of the seat belt) The OBD2 system is looking for a 1.7-2.75 ohms reading in that circuit in wire set attached to the seat itself. The two wires in the seat go to the pyro tensioning device connector. The device in the pic below shows two wires where the seat side wire set goes.
Disconnect the seat wires set from the floor harness and measure the resistance across those two seat side wires. A reading outside the proper range will indicate the pyro device is not functional and thus will display the airbag light and Error Code 1213. If the reading is within spec then the problem is most likely in the wire connections.
If you watch the airbag light when you first switch on the ignition it should start to flash four times, pause, then seven times. This represents 47 - this is also an indicator of what is causing the error - 47 is the light flashing code for the passenger seat pretensioner out of spec. Any other light flashing sequence points to a different error source per the chart below.
The seat belt buckle ITSELF has no electrical connection on the PASSENGER side. The DRIVER side buckle does have a switch in it since failure to latch the driver belt will flash the fasten seat belt light.
