An apparatus and method for aiding in the assembly of a substrate to a vehicle body structure wherein the substrate includes a cable configured to attach to an electrical component mounted onto the vehicle body structure. The substrate includes a retaining device selectively disposed on the substrate and configured to releasably retain the cable. The retaining device is disposed on the substrate so as to position the cable along the substrate in such a manner that the cable will not interfere with the attachment of the substrate to the vehicle body structure. Accordingly upon attachment of the substrate to the vehicle body structure, the cable is manually removed from the retaining device and attached to the electrical component thereby preventing the cable from being trapped between the substrate and the vehicle body structure during the assembly process.
