Wiring diagram trillium 4500

[Bobby Kirk]

Does anyone have a wiring diagram for a Trillium 4500?
I am trying to restore mine. P O took out most of the wiring.
Thanks ,

Prickly Bobby, are you referring to the tow harness wiring or the interior wiring or both??

The Trillium 4500 wiring (I have a 1978 Trillium 4500) is basically the same as Scamp wiring and its very simple. For interior wiring, black = positive and white = negative. The original "power center" simply has a push button AC circuit breaker and push button DC circuit breaker on the front panel. Also on the power center front panel is a switch for toggling between battery power, shore power and OFF.

Thanks for the input John. The "original power center" has been replaced and the battery with all its connections removed so wondering how the battery was put into the circuits.Also realized the d/c to the fridge is disconnected.All the lights are working fine as well as the a/c outlets.

I have a ‘77 4500 and like you discovered the POs had modified the wiring over the years. Over the years I’ve had mine I have put in new wiring from the hitch through to all running lights, brakes etc. I used a 7 pin wring harness in case someone wants to install electric brakes at some point.
The 120 VAC circuit was also changed, but I have left it alone. I did isolate it from the 12 VDC circuit completely. I charge my battery with a solar panel. I kept the old transformer unit, but removed the actual transformer and installed some circuit breakers inside for the 120 VAC circuits running to the fridge and outlets.
Hope this helps!

Prickly Bobby,

- Original 12vdc interior black wires should attach to the battery positive post, and original interior white wires should attach to the battery negative post. EDIT: Of course, there should be a 12vdc fuse panel in between the 12vdc circuits and the battery.

- Every power distribution center/converter is different, so can't say how to attach "it" to the battery.

- Original 3-way fridge has AC, DC and propane modes. DC mode generally isn't used because the battery can only run the fridge for a very short time. EDIT: Some folks use the fridge 12vdc mode to run the fridge using tow vehicle power while towing.
