I have a "related" question about towing our new '89 Scamp
. This is a long post, so feel free to just read the red text to get a general idea. I hate to waste other's time! Our Explorer came with a tow package but we're getting a bigger hitch -- no problem. Also, it came rigged with a flat four plug and the Scamp
has a flat 7 point (6 around 1 I think). So at the trailer place, we got what I think is a "T One" converter to go from four on the Explorer to seven on the trailer.
It's pretty obvious how it works -- the trailer plugs into one end that will be mounted on the hitch; and the Explorer's flat four goes into the piece on the adapter that it will fit.
It's at this point that we have questions. There are four additional wires coming out of the "vehicle" end of the adapter. The colors are white, black, yellow, and blue. As I understand it, the white is a ground, the black is for batter power, the blue is for brakes
, and I'm GUESSING that the yellow is like purple -- for auxiliary. Question One: Am I right about my colors on the four extra wires on the adapter? white-ground, blue-brakes, black-battery power, yellow-auxilliary like purple.
So we're not going to do the brake controller yet, but we will eventually. The ground is pretty self explanatory. I doubt we'll use the yellow. But we DO want to use the black so we can "charge" the trailer while we're in transit (i.e., keep the 3-way fridge
running off of DC power to keep food cold). So far, I have read that you have to run the black wire up to the battery
. At this point, things get foggy again. Question Two: Does the black wire from the adapter need to be connected to the positive or negative post of the Explorer's battery?
This seems like a big deal to me, but there seems to be some confusion!
Also, my mechanic wants to put a fuse in and I'm sure that's a good idea. The guy at the trailer place mentioned that, so no problem there. But I've also heard talk about "isolators" and I can't really figure out if I need one or not, or if the Scamp
already has one built in, or where to put one. I haven't asked my mechanic, so he may know but I figure I've written this much.... Question Three: Do we need an isolator, does the Scamp '89 16' already have one, where do we put it?
And with that, I think my questions will be answered. If you have a website or photos that can explain this well or ANY suggestions, we'd both be very thankful!
