Update: DIY guide is now up, DIY: How to install JDM Prius power folding side mirrors
I generally do not have time on a weekday to entertain Prius projects. Heck, I rarely have time on the weekend and it looks like I’ll have this weekend booked ahead of me. Today, I received my JDM Prius power folding side mirrors kit. It took about 1 week to receive them; 4 days to have the outer covers color matched to color code 8V1 and 3 days for EMS transit time.
The JDM mirrors are sold with unpainted OEM housing covers, but since I ordered a set of aftermarket 3-in-1 combo welcome winker LEDs, I paid an additional fee for a set of color matched mirror covers.
The auto-folding relay / controller module is aftermarket:
As I was returning from my local USPS office after picking up the package, I ripped open the switch panel on the driver side to compare the JDM mirror switch vs USDM mirror switch and their respective connectors.
‘lo and behold, the connectors are different and isn’t plug-n-play:
The USDM mirror switch plug is a 16-pin connector with smaller contact terminals. The JDM power folding mirror switch plugs into a larger 10-pin connector.
The mirrors’ folding function worked as I’ve tested them using a set of alligator test leads. There are two wires in the JDM mirror connector (blue and green) that controls the folding function. Upon closer inspection, these two wires actually occupy the cavities in the mirror connector that the USDM defrost wires occupies. They fold or retract the motorized hinges depending on the polarity of the wires, just like the JDM Honda Integra DC5 power folding side mirrors I’ve installed onto the Acura RSX. They (the power folding + and – wires) will need to be de-pinned out of the JDM mirror wire connector and isolated into their own dedicated connectors (I can reuse my Honda parts for this). There are also an additional pink wire and white wire which controls the JDM OEM turn signals. These will probably be discarded.
The 3-in-1 welcome winker combo LED comes complete with connectors and extension wires. The installation seems pretty straight forward and calls for tapping the lead wires from the 3-in-1 LED onto various function-corresponding wires from the vehicle harness (i.e. overhead map lights, parking lights and turn signal lights).
I’ll have some research to do on Toyota Information System between now and the weekend. I’ll most likely wire up the 3-in-1 combo welcome winker LEDs and power folding side mirrors separately and write up two individual DIY guides. Stay tuned!
