epoxy filled electronic converter are made ? I am shedding a little light on the subject here ( no pun in 10 did ). I also made a utube
of this, but for those instructables fans, here is how I wired my 2010 Honda Civic to a Harbor Freight utility trailer.
Step 1: This converter will require a pair of Radio Shack relays
as they can handle 10 amps and are 12 volts. If you have a lot of trailer lights you will have to size the wire and relay
load to your need. This instructable is more of a how I did rather than a how to. I could not find any information
on the high price trailer light converter kits on the web, so this is how I think they work.
I have built this system on my new (at the time 2004 Honda Civic) and it has served me with no problem, to date.
Step 2: Pinout of relay
Step 3: Electrical schematic
wiring as I only had one situation where a pinched wire blew the running light lamp.
Step 4: Connecting wires to brake tail and left turn signal
The brown wire by itself has a red tape around it
to indicate it is the brake light source. Yellow is the code for left side signal light (think yellow center line on the drivers side) and ( Green grass for the passengers side) code for turn signal and Brown for the running lights.
Step 5: Connection of right turn signal
Step 6: Connecting the 4 wire system to the relays
when the relay is de-energized. The cathode (banded end) is attached to the the source voltage, and the other
end is attached to the relay common.(white wire that goes to the vehicle ground lug on left side of the Honda Civic)
Note if the diode shorts or is connected in reverse it will blow the fuse. At this point I will say it is optional.
Step 7: Connecting the trailer side to the adaptor
flooring. The wiring, when not being used to connect to the trailer is stored inside the trunk and when the trailer is connected it
just has the trunk lid shut on it. This keeps the plug contacts from becoming weathered and just looks better than having a plug dangeling down.
