Add Electric Power Steering To Any Vehicle for $150 | EPS Conversion

Today I'm going to show you how you can add an electric power steering system to any car or vehicle. The advantage of using a Prius electric power steering system or other adaptive electric steering is simplicity. Unlike hydraulic power steering, an electric power steering conversion only requires 3 wires (power, ground and 12volt on) so no messy hydraulic lines to worry about. The Toyota electric steering systems are widely available on ebay and can usually be found for around $250. Alternatively you can use electric power steering from a Kia, Hyundai and even Nissan.
The EPS system I chose is from a 2014 Kia Soul. This DIY EPS conversion is perfect for muscle cars or any other system that lacks power steering. I knew I needed the EPS conversion on the dune buggy when I used a faster steering rate and now its like a new buggy.

Not sure how I stumbled on to this channel, but it looks good. Nothing screams 'my kind of people' like MIG welding steering components in flip flops.

[@NeoIsrafil]

Hehe yah, I do flux wire in pajama bottoms and sandals, seems the algorithm has grouped us all together.

[@Freedom_is_better_than_safety]

Just as a point of information, these power steering units have a small rubber gear inside that’s well known to deteriorate and “thunk” when you power them up and turn the wheel. If this happens, simply unbolt the motor from the side and inspect that rubber gear. If it’s bad, replace it and it’s fixed. Dorman sells the gear for around $12.

[@williamlanphar630]

Outstanding job man. I’ve been looking for ideas for my lawn tractor and this is giving me some ideas. Btw, I see you practice safe welding in flip flops like I do. Cheers

[@liquidlinda2708]

Man, you are a mechanical GENIUS!!!

[@icarossavvides2641]

2:40 ish, Just a few points of enlightenment. The input and output shafts are NOT solidly connected, they are coupled via a resilient coupling (this is a failsafe connection whereby if the EPS fails there is still steering control albeit without assistance). This coupling allows slight angular displacement between the input and output shafts. without a differential load you will see and feel nothing. Once there is angular displacement between the input and output shafts, due to steering system load, the differential is measured electronically and is used to regulate the amount of assistance the EPS delivers, the greater the displacement the greater the assistance. Hope that helps.

[@jimbobelectronics]

Just a little insight.... You can solder a wire into the connector without dissasembling the unit. Just tin the pin and the wire, and then just solder away. you can simply fill the connector hole with silicone after to seal it up. SAVE YOURSELF HOURS! :)

[@JasonSmith-utube]

Yeah I don't know why he would do all that disassembly when you consider it from the outside.

I'm just starting this same mod on my daughter's '63 Nova. I'm going to retain the column shift for the automatic by shortening the shifter mechanism and using a shift cable setup, (I think and hope). Failure is not an option but, just in case, I know where there's another column the same color. I got my steering gear, module, and plug from an '09 Corolla for about $100 at the local u-pull-it yard.

Great job. My china rhino clone just lost its electronic power steering. And dang wouldn't you believe it's going to be -24 In Minnesota the next couple days and I need to plow. It's really not that bad unless you have the front diff lock engaged

[@terriecotham1567]

Quick tip on connectors, there's two parts of the connector even on PC boards and if theirs a number or name or both at times its possible to find the connector and the part number for the mate. At times it takes a little work. But in the age of computers lots of data is online and its amazing at times. So dont give up to ease as some OEM parts may have the same connector PN or run of parts and you have to pin them down, Take the VPX Pro or Sport circuit Breaker replace panels for new aircraft. the connector kit is a few dollars and the pre wire kit with pins is a few 100 dollars and not a bad buy for some home builders or avionics shops as they come with the wires prie crimp and all the builder has to do is match the wire sise to the circuit and put them into the connector. But I looked at the VPX and was able to track down the connectors and then the pins for each connector and in a range of pins for the wire size of the aircraft circuit. If you a home builder the computer can do amazing things when tracking down parts And places like Y Tube can offer amazing advice for your next Ideal no matter how simple or complex

[@Tatertot_Tommy]

Just for future reference, you could also just connect the single wire to pin #1 in the exterior connector receiver, and then simply fill the remainder of the void in with RTV, or you could put a release agent on it and fill it in with some Bondo to make your own connector "pigtail".

[@Mr.EeToMyself]

[@aceshadow3077]

GREAT JOB A+ on the video Learned allot. I have a 1934 Plymouth car and I have purchased off eBay a Saturn view electric power steering I would like to put on this car. Looks very similar to the Kia you have. It came with the control module with a large red and black wire ( sure this is to battery) and the small plug with 3 small wire sticking out about an inch.

Do you happen to know if there are any of these EPAS systems that have 'return to center'. Thats something I know the prius doesn't have. Are there any of these that have better aftermarket operating systems so they aren't always in failsafe mode that anyone knows of? Awesome video, some really amazing content here, thank you so much.

[@Iowa599]

For "return to center" just run more trail. (caster is usually the easiest thing to change)

[@Tappar1]

With the Prius I believe you can put a potentiometer between some of the signal wires to adjust the strength so it isn’t just in failsafe, but the issue is usually it’s a variable signal from the ecu so it’s not simple to retrofit.

[@Iowa599]

@@Tappar1 there is no "return to center" assistance by the power steering rack… The idea of one is dumb, really dumb… If there is no input through the steering shaft, there is no assistance. None. Everything that happens is mechanical & caused by the tires & suspension.

Hey, if you're near Tennessee I can probably help you 3D print a housing for one of those connectors and then you can snap in a Molex or Dupont pin to fit the actual terminal. The first one will probably take a few hours to make, after that you can print them off for pennies.
