Question Wiring Connections Pinout List

Looking for help in locating a Listing of the Wiring Connection Pinouts for my 2023.5 Defender 90.

I’ve Googled the web, rented an hour on TOPIX, and even subscribed to Scribd without success.

can anyone point me in the right direction?

Many thanks!

Are you looking for actual PIN numbers on diagrams for each electrical connector?

I don’t think that exists

Heyo! Good news. Yes, it does.

The pin #’s are on the wiring diagrams in the official JLR workshop manual.

So for example, look at attached. I just randomly grabbed something. This is the trailer module. What I’ve circled are the pin #’s in the connectors.



What does not exist that I’ve ever found for L663 or modern Land Rovers is a list, like on an old P38 or D2, called the “Electrical Library” where they’d list each electrical connection or junction, have a picture of it showing the exact location in the vehicle and whatever other information about that connector... sign. That was great reference. But those cars also were a nightmare lol.

I’m assuming you don’t have this workshop manual. I have these both on my google drive...

4 cylinder P300 US market - Thunderbob this is what you will want
