Jaltest JTP05 - Round Male Pin (Ø 3 mm), Pair

The JTP05 is a pair of 3 mm diameter round male diagnostic pins — the largest round pin in the Jaltest multipin kit system. These pins are used for back-probing larger ECU connector terminals and power distribution connectors that use 3 mm cylindrical contacts. Common on body controllers, relay blocks, and heavy-duty ECU interfaces on commercial vehicles and construction equipment, the JTP05 completes the Jaltest round-pin coverage at the large end.

What These Pins Are For

The JTP05 3 mm round male pins are inserted into the appropriate terminal cavities for non-destructive back-probe access on larger connectors. Once in place, you attach the JDC10AM2 or JDC20AM2 multipin cables to route the signal. Larger connectors like those using the 3 mm round terminal type are found in power supply connectors, high-current relay blocks, and certain heavy-duty ECU interfaces across commercial vehicles and industrial equipment.
