The 325-002 is the specific solution for boaters adding a second steering station or replacing a failed sensor in an existing dual-helm setup. Its 1/4" NPT size is a common standard for many diesel and gasoline engine blocks. By using a genuine VDO sender, you ensure that your gauges provide the consistent, reliable data necessary to protect your engine from overheating.
Since this is a Floating Ground sender, you must connect one terminal to the "S" (Signal) post on your gauges and the other terminal directly to the battery's negative terminal or a dedicated ground bus bar. Additionally, avoid using Teflon tape on the threads; while the sender doesn't need the threads for grounding, the tape can act as an insulator and potentially cause the sensor to retain heat differently than the engine block, leading to minor reading offsets.
