100 / 105 Series LandCruiser Steering Wheel Harness & Clock Spring Kit

If you’ve fitted an aftermarket steering wheel to your 100 or 105 Series LandCruiser and the buttons or airbag don’t work — you’re not alone. Most of the cheap sellers out there have no idea what these Cruisers actually need.

At TUCKS Performance, we’ve done the homework. This kit includes the correct clock spring and harness setup to make your new steering wheel plug-and-play with your LandCruiser — no guesswork, no cutting wires.

Here’s what’s going on

Both the early (’97–’02) and late (’02–’08) 100/105 Series use a unique 12-pin combined plug.

Toyota ran all the wiring — airbag, audio and cruise control — through a single plug on these models, so the usual 10-pin Toyota harnesses don’t fit. That’s where this kit comes in.

Early 100 Series (’97–’02)

• Factory clock spring uses a 4-pin plug and won’t work with most aftermarket wheels (12-pin).
• You’ll need our replacement clock spring and correct harness to bridge it all properly.
• Some early models have a larger airbag detonator module in the horn pad — a quick fix is to source one from a 70 Series LandCruiser, 80 Series, or Hilux for plug-and-play fitment.

Late 100 / 105 Series (’02–’08)

• Also runs the same 12-pin combined plug, but pin layout and resistance values differ from most Toyotas.
• Our specific harness for this model ensures everything — including audio and cruise — functions as intended.

Stereo Compatibility

You’ll need an aftermarket stereo capable of reading steering-wheel-button inputs for audio and phone controls to work.
