    Hi all, posted an update to my other thread but wanted to put out a new one specifically in the electronics section for this ask. Long story short, I have a 2021 steering wheel that has the heat function that I'd like to install on my 2016.

    I tested the wheel before installing and compared the clock springs. Looks like I may be missing a plug on the harness for the clockspring. Will ask here and then in a new thread - does anyone have a diagram for the electrical connections on a 2021 prius steering wheel/clockspring? Everything else connected and worked fine, so my potential thought is if I manually run a 12v and neutral to the two pins on the 2021 clockspring, I can make a diy rocker switch to feed power manually to the heated steering wheel. Guessing this way I won't have the button lit up but it'll get the warmth flowing
