Installation & product FAQs

Plan your purchase and installation with these product-specific answers.

Main relay conversion: installation guide

Official JDI main-relay conversion guide. Relay layout and access vary by vehicle; dual-relay kits require their own supplied instructions.

Watch the original JDI video on YouTube

How do I confirm the right version before ordering?
Match the vehicle, model year and connector option in this listing. If your wiring, engine or ignition has been changed, contact Speedzone with those details and clear connector photos before ordering. A video showing a similar car does not confirm your exact fitment.
What does the conversion replace?
It replaces the factory main relay with a serviceable Bosch-style five-pin relay and adds a kill-switch connection.
How does installation work?
For a matching application, JDI describes unplugging the original main relay, connecting the conversion harness in its place and connecting the supplied kill switch. Access to the original relay varies by vehicle.
How long is the kill-switch lead?
JDI specifies a six-foot lead, allowing flexibility when choosing a secure mounting location.
Must I use the kill switch?
JDI states the conversion can also be used without the kill switch. Follow the supplied configuration instructions.
Is this the same as the Ghost Key kill-switch accessory?
No. This is a main-relay conversion with its own kill-switch arrangement. The separate Ghost Key accessory is for the Ghost Key push-to-start system.
Who can help if I am unsure?
Contact Speedzone with your order number, vehicle year/make/model, selected kit and photos of the connectors. For manufacturer-specific wiring guidance, use JDI technical support. Follow the instructions supplied with your exact kit revision.

*In stock and ready to ship*
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). 
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 could also be used without the kill switch if you so choose.

Great product hi quality except the relay the is cheap. About double the price it should be tho $90 should be $40-$50 max shipped with protection. If it was a good value and a good relay I would have given it 5 stars
