Plug and play harness
 

I've seen a plug in harness for the LT series that lets you plug the ecu into the stock harness.

Will that plug in harness work with my MT8?? I like the idea of a plug in ecu like the Apexi PFC and don't want any hassles rearranging wires and soldering things.

One more thing, what is better a MT8 or a LT8? Which one is recommended for a modified FD?

The Mt8 Is just a fuel computer while the LT8 will control fuel and Ignition. IMO the Lt8 would be the best choice for full tunabilty. Im not sure if the Plug and play harness will work with the MT8, check www.microtechefi.com the info might be on there.
