This replaces your factory main relay with a standard Bosch style 5 pin relay that is much more reliable than the factory relay, which is known to fail and are expensive to replace ($65-$80 for a new main relay).

This makes the vehicle more easily and economically serviceable. 

Should you ever need to replace the 5 pin relay, they are much less expensive and are easy to find online or at any auto parts store ($8 to $12). 

JDI has also integrated a kill switch that will disable the ECU and fuel pump.

The length of this kill switch is 6FT

Fully Plug and Play! Install is very easy! Simply unplug the factory main relay and plug this in, in its place. Then, plug in the kill switch and hide the switch well for maximum security. 

Note: This could also be used without the kill switch if you so choose.
