The taillight bucket assemblies are reproduced today. These production housings have slight differences in the location of the mounting legs. The kit is supplied with a second set of templates that define the circuit board mounting holes based on these differences. Be sure to select the correct set of templates based upon whether you are using original or reproduction housings. It is important to select the correct template before drilling the circuit board mounting pilot holes as defined in the next step. Because of this difference in housings, we recommend that you drill small pilot holes and test the fit of the circuit boards before drilling the final 0.32 (5/16)-inch mounting hole.
Center punch the eight holes to be drilled in the housings and drill a small pilot hole to test the alignment of the boards. Once the alignment of the boards is correct, drill the pilot hole out to 0.32-inch (5/16-inch) in the corresponding places in each housing. Be sure to remove any remaining burrs from all holes after drilling to ensure a proper fit of the retaining rivets.
Each circuit board has a DIP switch located on the rear of the board. This switch determines the operation of the LED lights on the board as either sequential or standard. The board is shipped with the DIP switch in the up position indicating sequential operation. It is recommended that all DIP switches on all the circuit boards be set to the same setting.
Route the wires from each circuit board through the existing light socket holes in the taillight housing. The metal mounting brackets on each circuit board should line up with the mounting holes drilled in the housings in Step 5.
The circuit board retention brackets are secured to the housing, using the two-piece plastic rivets supplied in the kit. The rivet has a male and female end. The male end must be installed from the outside of the housing and the orientation of the female end must be as shown in the photo. Before installing the rivets, the brackets can be slightly bent to rest flush with the housing.
This is how the housing should look after the circuit boards are installed.
Notice that the DIP switch is accessible through the original light socket hole if the LED circuit operation needs to be changed.
Each of the four grommets must be split before final assembly around the wires and plugging into the taillight housing. If your grommets are not already slit, use a new sharp razor blade and cut them at this time.
This is how the completed circuit board installation into the taillight housing should look before the lens is installed. The grommet on the left was not plugged into the housing to show how the wire will sit inside the grommet before plugging into the taillight housing. The housing shown in this picture is a standard body taillight housing that has the additional center hole for a backup light. If you are installing the kit in a standard body housing, you can use one of the supplied backup light sockets to retain your backup lights. This will be explained during the harness hookup instructions.
