Do you have a 1990 NA Miata?
Do you want to put a removable steering wheel hub on it?
This part replaces the "Clockspring" wire mechanism that connects the airbag and horn wiring to the old steering wheel.
Additional parts:
- You'll need a little piece of brass, bent to form a wiper. I used K&S Precision Metals #8240 0.032x1/4" brass strip. Commonly available in US hardware stores.
- A #4 (3mm) wood screw to attach the wiper.
- A 3.3Ohm resistor to delete the airbag and silence the dash light.
General instructions:
- Remove the clockspring mechanism, wiring harness and all.
- Cut the wire leads into and out of the clockspring flush with the mechanism
- Rewire them back together.
- Bridge the airbag wires with the 3.3Ohm resistor
- Zip-tie the new wiring harness onto the adapter.
- Cut and bend the brass spring. See pictures.
- Assemble your detachable hub, checking the wiring and contacts as you go.
Good luck!
