Review on 12-Pack Automotive Relay Kit With Interlocking Harness Socket Holder And Heavy-Duty Pigtail - IRhapsody 4-Pin 40/30AMP SPST 12V Relay, Ideal For 12-Volt Applications by Scott Yenson

Used 6 of these relays on 2 separate Compustar Remote Starts. One for a 2004 Mercury Grand Marquis and the other a 2008 Lincoln Town car. The Town Car needed 3 relays, one for lock, unlock and trunk. The Marquis also needed 3 relays, one for lock, unlock and accessory heater blower. These relays are very well built tough and high quality. I will be ordering another pack of 6 just incase another family member wants me to do a remote start on their vehicle. Overall, highly satisfied.
