Hello & Welcome,
Are you looking to replace the switch on the brake pedal?
No - that is the only switch. I just wanted to verify that is what we are working with.
Let me grab the instructions and send the on to you.
Back soon, Greg A.
Here are the instructions.
Before servicing any electrical component, the ignition key must be in the OFF or LOCK position and all electrical loads must be OFF, unless instructed otherwise in these procedures. If a tool or equipment could easily come in contact with a live exposed electrical terminal, also disconnect the negative battery cable. Failure to follow these precautions may cause personal injury and/or damage to the vehicle or its components.
Let me see if I can get the instructions for disabling & enabling the SIR.
Here are the procedures to disable & enable the SIR system.
With the AIR BAG Fuse removed and the ignition switch in the RUN position, The AIR BAG warning lamp illuminates. This is normal operation, and does not indicate an SIR system malfunction.
I hope this helps.
I know getting in there is hard but it can be done.
You might want to remove an insulator panel or two, to get more space.
