I needed a forklift part and wasn’t sure which one fit. They asked for the model and serial number, got back to me quickly, and made sure I ordered the right one. Really helpful.

Frequently Asked Questions
Q: How do I use the tester to find a faulty circuit? A: Plug the tester into the trailer’s 7-way round connector, activate the truck’s light functions one by one, and watch the corresponding LED—if it doesn’t light, that circuit has a problem.
Q: Does this tester work with all 7-way round pin connectors? A: It is specifically designed for IPA 7865L connectors but works with any standard 7-way round pin layout; always confirm your socket pinout matches the tester legend.
