Currently, I have a lifted 2019 AWD-e XLE and I'll need to get summer tires next month.

Right now, I have the 195/65/R15 winter tires. I'd like some even just a little bit bigger.

For some reason, the calculator I use hasn't been able to load properly for a week.

Looking for comfortable, fuel efficient, slightly taller tires. Don't mind paying extra. I drive to trail heads often, and the extra height helps me regardless.

Your time is appreciated.]]> Wed, 14 Jan 2026 13:33:40 +0000 https://priuschat.com/threads/clearance-lamp-wiring-on-a-2022-le.258487/ https://priuschat.com/threads/clearance-lamp-wiring-on-a-2022-le.258487/ invalid@example.com (PAW) PAW
I removed the flat black plastic panel on the front bumper and found this connector.
I assume Red=power, white=ground, green=turn signal.

Can I hook this up and have working lights there?
Parts I think I need:
*Cord Assembly81935-47060)
*Front Bumper Side Molding (Right Hand 52712-47060)
*Led Illumination Lamp Assembly (Right Hand 812A0-47020)

Am I missing anything?

Can you replace the stock lithium cells in the gen 4 with custom more dense cells that match the nominal voltage?

The new lithium cells would match the stock lithium cells in number and in voltage, meaning there would be 56 cells and each cell would be rated at 3.6 nominal voltage just like the stock gen4. The total nominal voltage would also match the stock battery: 201.6v....

However the overall capacity would be...

So! I have a large, mostly empty cardboard box with coats and boots I need to carry around, and I'm looking for suggestions on how to handle it. I'd rather not have it go flying around if I get into a fender-bender.

Here's what I've thought of:

Is there a fuse to pull or something to make sure it doesn't get switched back on?

Has anyone found a third-party storage box to place in the trough?

I'm trying to add some extended front and rear wheel studs on my 2022 so that I can safely run slip-on spacers.

I see various places listing extended wheel studs for Gen 3 (such as ARP), but when I change the model year to 2022, it says they don't fit.

A) Can anyone confirm 3rd and 4th gen front and rear hubs are effectively the same for wheel stud fitment?

Rock Auto does list Dorman part # 610266 for both 3rd and 4th gen, which is promising.

B) If they're different, has anyone...

Anybody got an easy (I'm disabled so no DIY) way to raise the back level a few inches to take a nap in the back?

Are there any hard to find storage compartments?

I have a 4th gen Prius (2016) with the gps unit from factory. I dislike the stereo (mostly because of the absence of apple CarPlay). I a, considering replacing it with a Pioneer AVH-X8700BT

Do you know if there is a way to get CarPlay installed?

If not (I am almost sure it is), what cables, accessories I will need for this replacement (to keep the reversing camera, steering wheel controls and gps/navigation) unit working

Thank you.

On my squashed Prius there was a trick to (IIRC) put (red?) translucent film over a sensor on the rear view mirror, and to rotate the mirror 180 degrees.

Do I want to do this on my (not yet delivered) 2021 Prius?]]> 7
