The module's wiring comes tape flagged to aid you in grouping the wires together during installation. Plus, like all Painless wiring products, the wires are labeled every few inches with application and circuit number. The instructions even tell you what circuit to connect the wires to if you already have a Painless harness in your car. The bell chime is a simple two-wire connection that requires shortening the wiring to length, and installing the supplied ring terminals. You can drill a mounting hole for the chime, or tie-wrap it to a dash brace or existing harness for mounting. We opted to make a simple aluminum bracket for it that will attach to the base of the dash, allowing easy access to volume adjustment via the rotating cover.
