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...

Without significantly ruining handling and risking safety, what is the smallest wheel I can run on a Gen 4 Prime that clears the brake calipers, while allowing a narrow (read: skinny) tire with taller profile?

I understand there will be a slight speedometer...

I'm assuming not -- but thought to ask in case someone else has had this problem.

Running the power wire all the way from the back of the vehicle through the firewall to the battery seems to be (for me) very difficult. I'd prefer to use a fuse tap on the interior fuse panel. There are a few unused slots (12, 18, 23, 28, 29, 30) on the...

I bought one on Amazon designed for the Gen 4 but the material interferes with the console latch.

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?
