Toyota Prius headlight ballast replacement 2004 2005 without splicing

Toyota Prius headlight ballast replacement 2004 2005

I have spliced many wires over the years. I chose not to attempt to splice this high voltage cable.

Why? The HID output is a high voltage -- maybe 80v? maybe higher like 25,000v to start the arc:

Those voltages are well beyond the typical 600v rating of normal splicing methods -- certainly beyond the rating of simple heat shrink. In addition, Toyota went to a lot of effort to shield the wire with an external metal braid.

For these reasons, I chose not to cut and splice the wire. That I why I made the video.

It is a bit of a challenge to get the bulky shielded high voltage connector through the headlight housing around the reflector so you can either replace the ballast (although the 2004 and 2005 ballasts last a long time) or, as in my case, move the working ballast to a new headlight.

I watched Auto Buddy's (    / @autobuddy7985   ) video
   • Toyota Prius headlight ballast replac...   and tried to follow their instructions. I finally got it but it was a struggle. I hope this video makes it more clear that it can be done by removing both pieces of the adjuster.

Sorry for the crap video work and non-existent editing. It's really what you expect from a small unmonetized channel though, isn't it?

Peace.
