Radium is excited to release another new product, plug and play ECU connectors for all Lotus Elise/Exige 2005-2011. We worked long and hard over an 8 month period  to source and procure these hard-to-find connectors and we are now offering them for sale individually to the public. These connectors play a key role in our up and coming EMS solution that will be offered for our turbo kits for the Lotus Elise/Exige.

These connectors are extremely useful in making a plug-and-play ECU harness for just about any aftermarket engine management system. In order to install a stand-alone engine management system without a connector like this, a completely new engine wiring harness must be constructed, or the factory ECU connectors must be cut off of the OEM engine wiring harness and 3rd-party aftermarket connectors installed.  With these connectors, the OEM wiring harness can be used without modification, saving time and money.
Normally, parts like these are only available to major manufacturers in extremely large quantities. We worked directly with some of the best distributors in the country to locate and special order these parts.


These 80-pin header connectors are for the 2005 Lotus Elise that uses a one-piece ECU connector. These connectors are the same exact parts used in the construction of the OEM engine control computers.

2005 Elise connectors can be puchased here: Radium Store

We also have the 2-piece connectors used on the 2006+ Lotus Elise and Exige. These connectors are just as difficult to source and require large purchase quantities.

2006+ Lotus Elise/Exige connectors

2006+ Elise/Exige connectors can be found here: Radium Store

Constructing a harness using connectors like this can be easily done be straightening the pins on the backside of the connector and soldering wire directly to the pin, and finishing off with shrink tubing.


These connectors are all in stock now and are the perfect compliment to your custom engine management solution.
