Installing American Hard Bag Saddlebag Amplifier wire harness
The wire harnesses are broken down into several parts and packaged individually.
This is the harness that is routed into the saddle bag. This harness contains both positive and negative power cables (red & black), remote amplifier turn on(blue), input signal (RCAs), and speaker cables.
All of these cables are pre-terminated for you on the end that exits the bag. These connections should be placed under the side plastic covers that are located directly in front of the saddlebags under the seat.
A standard harness has power, ground, remote turn-on, and two channels of RCA exiting the bag . Speaker runs and extra RCA channels can be added to the harness as options. Some custom ordered harnesses are too large to fit under a single wire clamp (see wire clamps below). In these cases we supply a second wire clamp and we also wrap the harness as two parts instead of just one.
Speaker Wire Runs
Speaker outputs are used to run speaker wire to various sections of the bike such as: up to the fairing, down to lower fairing speakers, into the opposite saddlebag, or into the tour pack.
There are two sets of two channel speaker cables. Each set is encased in a white cable. Inside these white cables are four speaker wire conductors. The colors are as follows:
Red = Positive
Black = Negative
White = Positive
Green = Negative
You can use whatever speaker color arrangement that you like. We prefer to use Red/Black for right and White/Green for left.
Inside the bag that is opposite of the bag containing the amplifier, the speaker cable will have four conductors instead of just two. This is because many people run two speakers in each bag. If you do not need these extra conductors, simply cut the ends back and tape.
Blue Rings on Cable Ends
Crosslink cables are marked with a blue ring around each end (end that goes into the bag and the end that plugs into the bike) to help you keep track of each cable.
When more than one set of RCA cables have been ordered one or more sets are marked with a blue rings to identify which channels they belong to.
Mounting the Cable and Cable Clamp to the Bag.
A stainless steel wire clamp is included in the kit. This clamp covers where the harness enters the bag and also acts as a strain relief device, holding the harness in position.
The exact position of the clamp on the bag is not critical. The clamp should be near the front of the bag a couple of inches from the bottom. If you tilt the wire clamp slightly back towards the rear of the bike (opposite of whats shown above), the wire run actually flows into the side plastic nicer.
Drill a hole just big enough for the harness to be threaded through. Place the harness in the bag and temporarily place the bag on the bike. Adjust the position of the harness in the bag so that all of the connectors reach a suitable position under the side plastic of the bike. A typical distance between the wire side of the connectors and the point of the harness that enters the bag is about 14". Note the harnesses exact position and remove the bag from the bike. Silicone the wire hole from the outside of the bag. Use just enough to make a seal. Pre-drill three holes for the clamp screws and fasten the clamp down over the harness. When done right, no silicone is visible and the bag will remain watertight.
The power harness is the part that connects the battery to the bag. On one end there are chrome plated ring terminals for connecting to the battery, on the other end there is a high power quick disconnect for connecting to the bag. The fuse holders are also a part of this harness component.
The fuse holders are positioned on each power harness in such a way that the fuse holder can be located in either the left side plastic or the right side plastic, or for bikes that are '08 and earlier, the fuse holder can be located in between the frame rails (center) in front of the battery location.
Backbone Upper Fairing Speaker Harness
A standard harness comes with a Backbone speaker harness. This is a two channel harness that is routed from the side plastic where it is connected to the bag, up under the gas tank and out to the fairing of the bike.
Lower Fairing Speaker Harness
The lower fairing speaker harness is a three piece harness that runs the length of the bike from the side plastic bag connection up to the main fairing. At this point the harness has two 2 pin connections that get located behind the headlight. The second piece of this harness is two harness that run down each side of the crash bar to the lower fairing speaker pods. The third part of this harness is an additional four conductor length of terminated cable that exits the bag containing the amplifier alongside the main amplifier harness. This cable terminates in the side plastic along with the other inputs and outputs of the main harness.
Crosslink Speaker Harness
The crosslink is a three part harness that is used to route speaker lines from one bag to another. This is the harness required if you have speakers in your bags. The harness consists of a speaker cable with quick disconnects on each side that runs from the side plastic on one side to the side plastic on the opposite side of the bike. The second part of this harness is a speaker lead that runs into the opposite bag. The third part is a harness that exits the bag with the amplifier in it. This harness also includes a second wire clamp for the second bag. This harness can be run either in front of the battery or behind it. We prefer to run behind the battery. If you run behind the battery, you will want to make a loop in the cable (between the battery and the rear fender) to take up some extra slack.
Amplifier Remote Turn-On
Lastly there is a single blue wire in both the bag harness as well as the bike side. This wire is used to trigger (turn on) the amplifier when the radio comes on. This wire should be connected to an aftermarket radio's amplifier turn on circuit. If using the factory Harley radio or installing on a Road King (no radio), this wire can be connected to the bikes accessory circuit.
Make Life Easy!
Here is a tip that can make the whole installation go much smoother. Leave the gas tank off of the bike until the end. A key step in getting the plugs to fit nicely under the side plastics is to get the amount of slack right for the harnesses that run under the tank. If you keep the gas tank off of the bike, you will be able to make adjustments to the backbone wire runs (RCAs, upper and lower fairing harnesses). A half an inch of adjustment one direction or another can make or break the outcome of the end product.
