I prefer the Gen 1 in many ways to the Gen 2. I prefer the Gen 1 front end, Gen 1 interior to the new digital and square interior. Probably showing my age here a little.
But I do love the Gen 2 tail lights. I also love the removal of the rear Toyota badge and the fact that I can now remove the rear spoiler and fit any other unit without worrying about out the brake light.
So today, I installed the Gen 2 GR lights on my Gen 1.
Lights don’t come with instructions which put me on a path of discovery when I didn’t find much details here or other groups.
This thread is to help anyone else that might be doing the same thing.
Parts needed:
1. Lights - purchased mine from Lamspeed as I am in Australia. They are expensive for what they are. I was willing to pay the price.

2. from your local auto parts store:
3. 12v volt meter helps if you have one (not a must)
4. Tools: Electric drill, 24mm step drill (yes, you will need to drill a 24mm hole in your car. If that is a deal breaker for you, stop now 😉
5. Your favourite brew and an afternoon
Wiring:
Kit is NOT plug And play. The kit will come with a short wiring connector. This is just a short connector for the new centre light. It does not come with wires or instructions on how to wire in the new lights on the Gen 1.
Wiring process and instructions:
Wire connections:
Step 1: Drill a 24mm hole using a step drill

Step 2: install the supplied connector and water plug

Step 3: install the new centre light and connect the plug. Cut off the other end and install your newly purchased 4 pin connector of choice

step 4: create your wiring harness with black, red, blue and yellow wires that you will connect to the existing car connections

use the new cloth tape you bought and wrap all the wires nicely for a factory look and use cable ties to secure cables
Step 5: Feed your new wiring harness through the factory rubber grommets

step 6: lightbulb swap
The new lights don’t come with new light bulbs. Just the light shell. So you will need to twist remove the existing light and fit them to your new ones. This is easy to do.
The challenge is in the next step. The existing car connectors connect to the bulbs in the same way. However if you simply connect them in this way, the lights won’t work as intended.
You need to swap the BRAKE light with the DRL light. If you don’t do this, when you brake you will see the DRLs coming on and the brake light will be the DRL. You don’t want this.
All you need to do is swap the DRL connector with the Brake connector. To
Do this, you need to disassemble the connector so you can swap them around. It is not difficult to do, just need a small screw driver, a needle or other very thin long connector disassemble driver.
(If you struggle with this step ask a question and I can help)
Once you have swapped the plastic connectors the lights work as intended.
Step 7: wire taps
you have 4 connections to make
1. To battery negative or any other well ground earth point on the car of your choice.
2. Red wire tap to Brake light (easiest on the left tail light)
3. Yellow wire tap to DLR light (easiest on left tail light)
4. White wire tap to the reverse light (this is located centre (middle of the rear bumper)

Step 8: test and make sure the taps and lights work as intended.
DRL should come on with lights
Brake with brake
Reverse in reverse gear, etc.
Step 9: put the car back together in reverse order.
here are a few pictures of the finished car.
