AMP Research

I wanted to see if anyone else had been able to get this to work on a 2021. As far as I can tell there are 2 wires that appear to be different from the 2020 update. The violet for the drivers door and the violet /yellow for the passenger rear door don’t appear to be on the white connector. If anyone could take a couple of pics (I know its a pain) of the 4 wire tap connections in the passenger panel I would really appreciate it.

These appear to be the same:
Violet / White wire on the Blue Connector
Violet / Gray wire on the White Connector

These are the two that appear different
Violet Wire that should connect to the purple wire on the AMP harness
Violet / Yellow wire that should connect to the yellow wire on the AMP harness

This is the correct wiring for a 2021 JL 392. Also correct in the AMP Research wiring instructions, although it does say, " Note: 2018-2019 model years and 2020-2021 model years vary "

Only the Blue Connector harness has 1 wire connected to it. = Violet/White, and you connect the White wire off the wire harness that connects to the black box with the light on it, which came from AMP research (module).

All the others are connected to the White Harness. The white harness contains the other 3 wires you will be looking for.
-Violet to Violet (looks more dark pinkish to me, but could be the lighting).
-Grey to Violet/Grey (in the harness)
-Yellow to Violet/Yellow (in the harness)

I just installed a set on my 2021 JL 392 and they work perfect.

Some tips.
1. Disconnect the Blue Harness, the White Harness, and the Black Harness (uses no wires but makes it easier to get to the White harness). Basically disconnect all 3 of them from the BCM that is mounted to the Passenger Side under the glove compartment.

2. Three of the four wires are in the White Harness (Violet, Violet/Grey, Violet Yellow)

3. One of the four wires is in the Blue Harness (Violet/White)

4. Make sure you connect the White and Blue Harness back into the BCM once wired up. You should hear the Driver side and the Passenger side steps drop if you have the doors open, when plugging in the Harnesses to the BCM. The harness connections will clip in with the locking brackets.

5. Make sure your Black Harness is fully connected or the Jeep will not start.

6. Pull back some of the black tape that are wrapped around the harnesses, this makes it easier to identify the wires, and to splice in.

7. Exercise Patience

Good Luck
