electrical wire colors

[Lowpaidnurse]

I need help. I am replacing the lights in my 1978 Trillium 1300. I bought the submersible LED rear lights and LED lights for the inside. I cannot locate the wiring diagram in the forum. I need to know which wire colors connect to which. On the LED porch light I have, it only has one black wire whereas the trillium a black and a white wire. Do I ground the white wire and just connect the black? The LED interior lights I bought have a red and black wire whereas the trillium has a black and white. I am totally lost in the sauce on the left rear tail light. there are 4 wires on the trillium and only 3 on the light. Help!!

Unfortunately when you ask for technical assistance form the internet forums you'll get exactly the value you paid for.

If you can't be of any assistance, keep it moving. I asked for assistance for those willing to help. Keep your sarcasm. I can definitely do without it.

No sarcasm intended. You really need professional help to keep from burning something up.

The original Trillium's haven't been made for many years, predating the internet, so any such wiring diagrams are probably on yellowed paper in an old filing cabinet somewhere, lost in space and time. While Outback has apparently resurrected the brand name, I doubt their current wiring would match your 40 year old wiring.

many RV's use household wiring colors, where white is ground or negative, and black is live or positive. a lot of DC stuff instead uses black as ground, and red as +12V.

since we have no idea what fixtures you have, its pretty hard to be any more specific. I would be in there with a volt meter triple checking everything before I attached anything at all.

Thanks. I figured it out.

Christine, if your Trillium still has the original wiring throughout, then the wire color coding is the same as the Bargman 7 blade wire colors:

white = common ground, battery negative
blue = electric brakes
green = tail, license and running/marker lights
black = battery charge, battery positive
red = stop and left turn signal
brown = stop and right turn signal
yellow = extra aux. terminal, reverse lights

what about the internal circuits on the various DC fuses ? are they color coded in any particular way? or did they just use black for all 12V circuits with white for grounds ?

All internal circuits in my 1978 Trillium are just black + and white -. There is a single DC circuit breaker (not fuse), but the only DC accessories are the lights (changed to very low amperage LED) and the fridge DC mode (never use in DC mode). I have since added an LP detector and USB outlets. I really need to add a DC fuse panel or breaker panel, but so far just using terminal blocks.

There are line fuses under the front bench. I haven't determined their purpose, I don't use a charging wire, and haven't had any problems.

I replaced the original flaky transformer with a DC power supply.

If you plug trailer power from truck you can test the wires to wires, they will only lite up one way. Get to light before making it permanent
