Dual Main Relay Conversion with Kill Switch

*In stock and ready to ship*

This replaces your factory main relay with standard Bosch style 5 pin relays that are much more reliable than the factory relay, which is known to fail and are expensive to replace. This makes the vehicle more easily and economically serviceable. 

While a main relay conversion can be done with a single relay by removing the redundant ground and trigger wires, this conversion uses two relays to precisely replicate the function of the factory main relay. 

This works in factory, non-modified vehicles and is recommend for vehicles that are running an aftermarket ECU or vehicles that are tuned beyond stock power.

Future-proof your build today!

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

We have 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 can also be used without the kill switch if you so choose.
