A little.
Hard parts were working out how to properly retain the collapsing feature, and then getting the speed control stuff working.
Welding up the mounts, etc wasn't hard.

Oh... no cruise control.
By speed control, i mean getting the EPS to change assistance power depending on car speed.

It's quite nice.
In car parks its a one finger turn, but at highway speed its heavyish and holds straight.

Yeah it does.
GPS speedo might not react to speed changes quick enough :(
It really does need a gearbox speed sensor, or a sensor on a hub or tailshaft.

Well I won't need the speedo from the box so I'll track down a sensor for w58 and use that looks like I'll have to find some wiring diagrams and go nuts

Wiring is easy.
Give it battery power, ignition power, and CANBUS signals (from the box i make), and its done.

Get it from a zre152.
Make sure you get the full steering column and the EPS control box. Also you need the two connectors that go from the EPS control box to the body loom (cut the wires).
Make sure the wires from the control box to the motor on the column are not cut.

I doubt there will be, it's too new a model.
I got my rav4 unit from just wrecking. From memory they charged less for it than I thought they would.

These old toyota steering racks seem really hard to come by, I think I need to start looking for alternative/modern car options with more accessible parts.
