I just purchased a 1998 Kiefer Bravo 2 horse. The transporters said the lights weren't working, so a friend removed the previous 6 wire round (wish that hadn't been done!). We've been trying to rewire to a 7 pole flat that fits our trucks with no success. The colors don't match any diagrams. I have red, black, blue, brown, green and yellow - no white for ground. Kiefer at first said blue was the ground, black running lights, red batter, yellow left, brown brakes and green right, but wiring according to this does not work. I called back and they said the usual green equals running, red left, ground white (I would need to add this they said), blue brake, brown red, and black battery. Wiring according to this does not work either. All I get is brake lights, no turn signals or running lights. Anyone know what the wiring color coding is for Kiefer??????

Disconnect the trailer from the truck, and use a battery to test the wiring on the trailer, I usually ground to the trailer first, then check the circuits and mark down the color, there isn't a brake light wire, what you will get is the bright light on either the left or right, that will be the turn signals for each side, you will get the running/marker lights, you should get the electric brakes(have someone stand by the wheels and listen for them to engage) with 6 different wires you should also have a circuit that may power some lights separate from the marker/running lights, and the last wire will be your ground(you may find it by it sparking when you tried to test it.:-}) Then you can wire the trailer plug. I have pulled many trailers that were wired incorrectly, and this method is the easiest way I have found to figure them out.

When I have to rewire a trailer plug, I perform a similar test as HB, but use a battery charger instead of a battery. I clip the charger's ground to the frame, and then touch each of the individual wires with the hot lead to test their function.
The blue wire is generally used for the brakes, and as was stated, sometimes make a noise when they're activated. When you touch the trailer ground wire, you will get a sharp spark and the meter will jump. These wires are generally the heaviest you'll find in the bundle. The running lights are easy to spot, and with these three wires discovered, it becomes an easy proposition to identify the rest by elimination. The truck's power wire can be usually spotted by turning on the LQ or stall light switch, and when the interior lights illuminate, you have identified another wire. The left and right turn indicators are easy to spot, just use a piece of masking tape to identify each wire as you discover its function.
You will have to know the individual functions of your truck's plug wiring, and match your trailer plug to it. In all it's not a bad job, and usually only takes a few minutes.
