OEM Replacement Wire Harness for Espar / Eberspaecher Hydronic S3 CS Heaters
Keep your heater running reliably with this genuine Espar / Eberspaecher OEM wire harness (P/N 20.2900.70.0013). Designed as a direct drop-in replacement, it restores proper electrical connections between the heater control unit and components — no splicing, no adapters, no guesswork.
Compatible Models (12V & 24V):
- B5E — 20.2051.05
- D5E — 25.2933.05
- D5L — 25.3009.05
- D6L — 25.2972.05
Why OEM? Aftermarket harnesses can introduce resistance mismatches and fault codes. This is the same harness Eberspaecher provides with the heater installation kits — guaranteed fit and function.
