Match PP-UNI 1.48 MB – universal 48-pin upgrade harness for Mercedes
The PP-UNI 1.48 MB is a universal 48-pin UPGRADE cable harness for connecting multichannel MATCH or HELIX DSP amplifiers to factory-installed premium sound systems in Mercedes vehicles. It is a 30 cm extension with full pin assignment that plugs into the original vehicle harness.
The wire cross-section is chosen as large as practical to minimise conduction losses, and the harness is manufactured to automotive industry standards. Since the assignment plan of the factory amplifier is needed for operation, installation by an Audiotec Fischer specialist dealer is recommended.
