Did the Trick!

Works great! Turns out that when I was installing it, I found out that the one I was replacing still worked, a wire had just come loose.

Seek alternatives

I bought two of these and both units have failed. The first one died after a week of use on my motorcycle. The second one died after just a few days. I fused and relayed the power source to ensure longevity but it did nothing to stop these from dying prematurely. I would not recommend these at all.

Great Car Alarm Addition

This unit can be a valuable asset to any car alarm system. It enables you to connect almost any accessory to your alarm. Once triggered the unit activates the choosen accessory. I recommend connecting it into a underbody kit, or strobbing lights, it provides a great visual effect that demands attention when your alarm is whailing. Additionally it's made by DEI so you know your getting quality, and reliability.

528T Relay

It was a little unclear when I purchased these relays how to connect them. After I received them and bench tested them I realized they would not work for my application. THEY CAN ONLY TRIGGER ON THE NEGATIVE SIDE.
