FREQUENTLY ASKED QUESTIONS
Answers to Popular questions

Why buy a relay box for power windows?

It’s all about custom wiring done right — power windows and power locks need pairs of relays to operate properly, which can be a real hassle with stand-alone relays. Our power window relay boxes make wiring easy, convenient and centralized, with added features such as built-in LED fuses and the ability for negative switching.

Can this relay box operate “normally closed” devices?

Yes! Power windows and doors need pairs of N.C. 5-pin relays for reverse motor operation. Our unique SPDT Bosch style relay boxes are specifically designed to connect power windows and locks. All you need to do is connect your switches and power windows / locks to the appropriate screw terminals. See the wiring diagrams for more information.
