I used a 4 pin male and female Molex plugs from a PC that they used to power fans and hard drives.

Thanks Larry. I picked up a new Molex connector and plan to splice it inline from the power head to the module.'
I was hoping that someone knowledgable would chime in on the effect of one or more of the torque sensors becoming intermitant or open.
I just might have to experiment the situation with the unit on the bench.

I had not seated one of the pins properly and the result was no assist. You know something is wrong because the relay in the ECU clicks immediately instead of the few sec delay that happens when you turn the key

Theres also a US seller, it's $10 more but in CA. Welcome to ePowerSteering.com It's the same as Bruno's, in fact Bruno recommends him as a US seller

Has anyone tried the one that is supposed to be "automatic" torque sensitive? I can't tell from the description if it is variable or just on-off. I sent them a message last week asking and never got a response.

I sent Bruno a question on this device, as I'm installing a VUE EPS in a Fiero. His reply was that for a street driven vehicle, the automatic would be better than the one with the adjustable Pot, so I bought one. He said that if it was going to be a track driven vehicle, then the one with the POT would be better- I guess for more adjust-ability Received it yesterday, so not yet installed. It installs by soldering one wire from the new controller to one of the 4 small wires from the EPS box to the Torque Sensors. That, along with power and ground, are the only connections required by the new controller. It also comes with a 6 prong pin to directly plug into the EPS controller box.

There is one more grey wire from the Automatic controller, that determines the "mode" you drive in. Leave it loose, and it's "medium" level of power. Ground it, and it's minimum power level. Attach a 100 ohm resister to the grey wire, and ground it, and you have maximum power level. This to me sounds like he's just eliminated the Pot, and gone with 3 fixed values. I hope I'm not wrong. I may regret not buying the cheaper version ( although I suppose I could always wire in a pot to the grey line, with 0-100 ohm resistance).

It will be a couple of weeks before my install is finished- hopefully others have some more experience on this to share.

EPS Installation Complete!

Wrapped up the installation of a 2008 Prius EPS unit on our '68 Coupe and test drove it. It is "perfect". It took about 12 hours to do the whole conversion from the '68 collapsible column and the only additional parts required were 10 gauge wiring, a borgesen 312500 u-joint for the lower shaft, a 40-amp inline fuse and three electrical connectors. We were somewhat worried about the feel at speed, but at 85 mph it is very stable. Can't wait for the upcoming track season. Thanks for all the information. Great Forum.

Congrats on the completion of your project.
12 hours, wow, I wish I could work that quickly, that or the Prius install is a lot less work than the Vue conversion.
Do you have any pictures, I am curious as to how much work it involved and how it looks installed.

I'm now torn between installing the Vue column I already have (didn't pay a lot for it) or finding a Prius version which is more expensive as it comes off eBay versus me pulling it from a local yard (no Prius' to be found in the yards around here). As a reference, I have a 69 Mustang.

Suggestions

If you plan to use the Prius in fail safe mode, the downside would be not being able to adjust it to your liking. If you run wide tires or have heavy steering to begin with, you may want the ability to adjust the amount of assist you are getting.

Just my two bits.

Got the basic install finally done, and it works like a charm up with the car on blocks.
Some final wiring clean up, rechecking all the bolt torques, the e-brake and steering wheel reinstall are next.
Leaving the O/E hydraulics on till I get to drive it.
There is noticable variation in the input force from no boost to full on. Looks like it performs as advertised - - so far.
