Mk2 Steering wheel replacement
by Pete Jones
Before starting, ensure wheels are in straight ahead position and
check that the MOMO boss has a rectangular cut-out in it for the horn
socket. (MR2 is different to the regular Toyota boss)
- Pull of the centre pad
- Remove the frame that the centre pad clipped on to by removing a couple of screws
- Unplug the horn wire
- Loosen the centre nut **DON'T REMOVE IT**
- Pull wheel sharply to free (had you removed the centre nut fully you would now have a broken nose)
- Remove nut and steering wheel
- Fit the boss to the wheel and ensure that the horn earthing ring is sandwiched between them both (this will come with the boss)
- Install the boss onto steering column in straight-ahead position.
- Cut the wire and plug off of the old horn push button
- Fit the 15 amp female spade connector onto bare end of wire
- Plug the wire into the horn connector and slide the spade connector onto the centre connection on the MOMO horn push button
- Connect the earth wire (supplied with boss) onto the other connector on the the MOMO horn push button and connect the other end onto the earthing ring on the boss
- Ensure that the centre nut is nice and tight
- Clip the MOMO horn push button into place on the steering wheel centre
- Check the horn works and ensure that the allen bolts on the steering wheel are tight
After a few days, check that the allen bolts are still nice and tight.
