The document center is where you can find it:

OK, after looking at it that is just wire color codes.
This one is the wiring diagram:

The wiring diagram in the document center is for a Trillium 1300, not 4500. Given that the power center is on the opposite side of the trailer on the 4500 vs 1300, it just isn't really valid for the 4500.


Does anyone have such a diagram, but for a 4500?

wiring diagrams for any given trailer are only approximate guidelines. things are often wired ad-hoc even within the same model year

And prior owners have had almost 50 years to make changes.


And the 1300 diagram is not laid out with actual locations. I bet the 4500 wiring is nearly identical. I think they used a similar POS electric control center. One of the best things I did to my 1977 Trillium was replace that control center, and add a removable power cord.


FWIW: All my knowledge about Trilliums came from others, in particular Dave Tilston and Randy Bishop. The upper right on the home page, click on manufacturers, then select Trilliums. You will get access to all of the threads on Trilliums.
