What it is
Complete pre-wired harness for the Pro Tune PR-8 ECU, the top-of-the-line ECU for engines with up to 8 sequential cylinders. The PR-8 uses two distinct connectors, and this harness covers both — Molex 48-pin (primary connector) and AMP Seal 23-pin (secondary connector) — with all cables continuously printed for identification.
