Starter Relay Kit Installation Instructions

Starter Relay Kit



We have developed Starter Relay Kit for all Mazda RX-7's. The "click, click, start" issue is a very common problem with the RX7, as the electrical components age the problem gets worse. Our easy to install Starter Relay Kit mounts next to the starter to ensure that the solenoid gets full voltage when you turn the key. We have developed this kit utilizing a completely waterproof 50 amp relay with a built-in resistor for voltage spikes, all terminals have heat shrink insulation for durability and protection. Works with all starters.

Please read and follow instructions carefully to ensure correct installation
