Electric Power Steering Conversion

Does anyone have any experience with this-type of kit?
Mustang Electric Power Steering Conversion Kit Early 1967

It seems like a pretty tempting option for those of us still running manual steering, but don't want to fork out the coin for a power rack and have to deal with the hydraulics.

If you care to read a LOT of posts, check out the homebrew $200 version of that setup here: Best $200 mod ever (EPS). Lots of info there about using that setup with about every steering option our cars have. Plus reports on how people liked the final results.

woh... that looks awesome.
I'd love to ditch my hydraulic power steering for electric if it gets rid of the noise. (also I hate spewing fluid if I need to steer the car with the power off)


78 pages though... whats the skinny of it?

a steering column from

• Saturn Vue - from 2002 to 2007
• Chevrolet Equinox - from 2005 to 2007
• Pontiac Torrent 2005-2007, not 2008
• Saturn Ion - from 2003 to 2006 - only in steering column with metal ECU case.



edit: half way through that thread... its.. a little too complicated for my brain.

I realize those threads exist, however I was just curious if anyone had used the pre-packaged kits like these? I know the low up-front cost of building a kit out of parts from other vehicles may seem like the best route for some, there are others who would rather buy a manufactured kit like the above.

I suspect that if you can't even make it through reading all that DIY thread then the DIY version is not for you and the kit in a box is the better choice. Some folks love nothing better than to fabricate and make things fit. Some are more at home just assembling things. Others prefer to pay someone else to do that sort of stuff. And the same folks may do the opposites in different circumstances. It's all good.

I love mine. The ONLY complaint I have is the loss of return to center. I have the saturn vue EPAS and I am planning on trying the Toyota EPAS to get back the RTC.

See the thread
Electric Steering with Fail-Safe: No eBay module needed. Pics & Videos !

The short version is ...
pull the steering column with electric power steering motor from pick-a-part.
cut up the steering column on Mustang (might not have to cut if 68 and above)
use couplers to join lower end of EPAS output shaft to Mustang gear box
use couplers to join upper end of EPAS input shaft to Mustang column (so you can use original steering wheel)
mount the EPAS under the dash
run some wires
badda boom, badda bing, electric power steering

very cool. so the electric assist has a better road feel (vs the OEM hydraulic ps)


what makes it not return to center, something to do with the electronic gear? and the Toyota ones dont have that issue?


I wonder if those full "costly" kits not have that issue?

I think that the loss of the RTC is one of 2 reasons. The Saturn EPAS is different than the Toyota, or the bruno box connection is causing it. I cannot say for sure that the toyota EPAS will restore the RTC, but I am willing to try and I have not seen posts about the Toyota losing RTC.

FYI, the bruno box is a eBay controller that you connect to the Saturn EPAS to tell it how much assist you want. On modern cars, the VSS tells the amount of assist (more at lower speeds), The bruno box replaces this and is a manual adjustment. It might be that the saturn epas loses it's RTC because of the bruno box. The toyota does not require the box, it has fail safe settings.

IF it is the bruno box causing the issue, then I would put dollars to donuts (ummm, donuts) that the CJ Phony kits would have the same issue. it would make sense.

All good points above concerning DIY vs buying a kit, however even if a kit is purchased, the majority of the work is in the modification of the original column to adapt it to the motor. Both DIY and the kits require you (the end user) to do that. It is nice though that the kits provide all the pieces to tie everything together vs buying independently.

For the RTC on the Prius unit, I should have an answer to that within a couple of weeks as I am almost done with the install. Column is done, wiring is done, ...just have to swap columns.

oh damn.... for the 1k kit you still need to modify the column?

thanks for summing that up.

Yes, as said, the only difference between the DIY and the kits is that the kits come with all of the pieces.

Here is the instructions from Mustang Monthly.

Yes, there is still a bit of fabrication involved. Although I am sure the kits provide all the pieces and instructions on where/what to cut on the column. Mine in particular was made to re-use the stock components on each end. Needless to say it was a learning experience but was not that difficult once I figured out which parts required direct attachment to the EPS and which pieces were 'decorative' to the usage of steering.

Here is a before and after picture to give you a comparison of the end result.

Question on this mod. Is the steering still available if the electric component were to fail? Would it still be like the regular old type steering?
