Intalled OEM EV switch

I just installed an OEM EV switch today. I got it from japanparts.com with the harness, and it came in about a week ago. I was a bit reluctant to install it because of all the talk about voiding the warranty plus I didn't want to perform open heart surgery on my new baby so soon without some good contemplation. But thanks to all the other EV mod threads I felt pretty comfortable and my worries about the warranty have been mostly alleviated. Thanks to everyone who gave their input especially Evan and Rick for their articles in the knowledge base. It was really easy. I even did everything without a soldering iron by pressing the wire for the HV ECU into the clip from the flasher plug in the steering column. To make sure the little knives in the clip cut through the insulation I tested the resistance between the clip and the other end of the wire and got practically none so it worked fine. Once I was done and had everything all snapped back into place I took the car for a spin around the block. I tried the EV swith and nothing happened so I came back and found out that when I tested the resistance for the clip I pushed back the connector in the harness so it did not make contact. Anyway it was an easy fix and I was glad too because I was starting to wonder if Toyota had changed something in the 05. To make a long story short the EV button works great and I am happy to have it.

Also I was amazed at how easily the dash came apart and went back together so I don't think I will have any problem installing the XM radio kit when it comes in next week. I ordered it from Metro Toyota in Cleveland, OH www.metrotpn.com the internet sales guy, Eddie, gave me a great deal $270 plus free shipping and no tax. That saved me about $35 if I had ordered it here in CA because of tax. Plus the parts and service guys in Sunnyvale aren't any help and refuse to say anything that will work in the Prius does. Another thanks to Evan for providing that link.

I have some pics of the install if anyone is interested.

Actually I had the same problem. If you email them for a quote for "04/05 Toyota Prius OEM EV switch and harness" they will respond back in a day or two and then you can use that quote number when filling out the form on their secure purchase page. It was really easy after that and I think you could probably get any other unlisted parts the same way.

Check out this page on their site.

Brian,

No problem just send me a private message when you are about to come and I will give you some contact info.

Yes you do see it right. The insulation goes all the way to where the pin would fully insert. If you look closely at the first picture of the wiring harness from the steering column you can see this is how the wire should be crimped in. This is because there are little knives in the crimp that slice through the insulation. It was not entirely easy to push it in but I got a resistance reading of 0.5 ohms. In comparison if you touch the leads of the ohm meter together you get 0.2 ohms. This tells me it is a pretty good connection with practically no resistance. Many other people solder the wire in, but I was trying for a more oem kind of look.

I will send you a private message check the link at the top of the page next to where the log out link is.

I don't have the quote information any more, but I just went to japanparts.com and they have a new page for Prius parts and accessories. Check out this link JapanParts Prius Page then click on the Interiors - others link and you can buy the EV switch and harness. Good Luck!

I know that the harness I got from them was oem. I took another look at the site and they now have the ev switch and harness priced together. Also the harness does not come with any wiring or terminal clips. It is just the plastic housing. This might explain the price.
