stock s14 column

stock s14 and equinox columns stripped down

s14 column and shaft

These are the important parts needed from the GM eps for the conversion.
red arrow- splined/female splined upper steering shaft will be welded to the upper part of the s14 steering shaft
yellow- section of the 3 bolt flanged tube that bolts to the motor will be welded to the upper part of the s14 steering column
green- output shaft from the electric motor and corresponding splined u joint needs to be welded onto lower s14 steering shaft before the firewall

you need to cut the female splined portion down below the flared area so it fits inside the steering column

welding/sleeving the female splined shaft to s14 upper steering shaft

upper column completed

U joint that connects to the output shaft of the motor welded to lower section of the s14 steering shaft

completed EPS s14 column vs stock

You need to heat the duct work here and slightly deform it to make room for the electric motor

installed

Here is the controller I used. Super easy to do.

and where I mounted the potentiometer. You can also see where the lower cover had to be trimmed some to clear the electric motor.
