Junction & Harness Connector Pinouts

As many of you are aware Toyota does not provide connector pinouts for junction box connectors or harness connectors making it quite tedious to see what circuits are tied together, I have compiled a multi-page spreadsheet that covers each junction connector & harness joining connector in detail including wire colors, circuit descriptions, and internal connections.

Currently I have only completed one based off the 05-06 wiring diagrams but it should cover up to 08, I'm going to start working on 09-11 and 12-15 when I get time.

If anyone spots any errors please let me know.

I also included the stitched together internal circuit diagrams with letters added for each set of connections.

Engine Room Junction Box


Interior Relay Box/Driver's Side Junction Box.
I found and corrected a couple errors on this one.


Interior Junction Box No 1


Interior Junction Box No 2

 

The engine swap guys are going to love this.
That’s an impressive amount of electrical information you’ve gathered there.


As someone that knows how much time and effort you had to put it to this, I just wanted say thanks buddy
I was looking forward to seeing this drop. Awesome job.

 

Thanks, hopefully someone finds it useful.
I was hoping 09-11 would be pretty close but it looks like quite a few pinouts changed on various modules.
