For folks that have a hard time turning their steering wheels at idle like me, this is the perfect pretty simple upgrade
get a donner entire steering column, a yaris 2007 will do. the pics are from after the install as i wasn't around to document it at the time
1: remove your existing wheel and column
2: remove/grind off the existing bracket that mounts the OEM column to dash. Alternatively, you can make a bracket, but I wanted a stock look.
3: line up new column and mark bracket spot to weld. this pic is with the yaris column installed using the factory mounting bracket and a L bracket to make it more secure from the tq of the motor
4: weld bracket and bolt up. reuse whatever adapters that didn't come with doner column as it is all the same.
5: ecu wise, you need a 60amp fused constant positive connection, a ground and on the yaris ecu, pin 5 and pin 6 (abs and ignition) needs to both see 12volt ignition to energise the motor. this allows with engine off to have 100% motor assist as a benefit also. Jacks A19 and D31 are the only places you need to wire up. the other jacks are all used by the motor.
6: i bought a unit that plugs into the ecu that controls the motor assist based on gps speed. that way the faster i go, the less assist will be given as it is supposed to be. because we have no canbus, the motor will give 100% assist at any speed. this is bad as at speed you want less assist.
