Good To Know

Q: How do I use this tester with an IPA 7865L connector? A: Plug the tester firmly into the truck-side or trailer-side 7-way round pin socket and watch the LEDs; a lit LED means that circuit is sending or receiving power correctly.

Q: Will it work on standard 7-blade RV connectors? A: This tester is built specifically for the IPA 7865L pin configuration; using it with a different 7-way layout may give inaccurate results.

Slight variation in finish or dimensions may occur between production runs, and fit can depend on serial number, so confirm compatibility before ordering.
