I have some metal film 1/2w 2.2ohm resistors in some car wiring. I'm concerned about the durability of this install and am seeking advice on how to protect the resistor once it's soldered in place. The obvious is heat shrink tubing, but it's there anything more substantial?

I'll be using these resistors in a custom pigtail that will plug into the car wiring. 3D printed housing? I have tried searching and I haven't found anything like that.

You can get panel mount resistors. They are usually rated at way higher wattage though.

I would probably just heat shrink the resistor. Your harness should be reasonably secure anyway.

I would question why you need a 2.2ohm 1/2w resistor in a harness in the first place though.

To fool the computer into not throwing an airbag light and disabling all the airbags. I have an early 00s car that swings double duty as street car and track car and when I pull the driver's seat out for a race seat, the airbag light shows up. Then I go through a rigamarole to reset the light once everything is swapped and plugged in again. It's a common mod, but just people usually cut up the harness. I'd like to keep things neat and tidy so I bought the seat side of the harness and want to cut the plug off, solder on the resistor and plug it in.
