The main relay is a weak point on the Miata. Both age and the electrical load from high volume fuel pumps conspire to take them out. If you're lucky, it'll fail while the car is parked - it just won't wake up again. If you're unlucky, it'll fail mid-corner in a race. Yeah, we've been unlucky. A failure like that cost us the lead in Targa Newfoundland.

This kit is designed to bypass the fuel pump relay. This provides an end-to-end wiring solution that is designed for higher loads, pulling power directly from the battery (or kill switch) and running it through 35A dedicated relay instead of the factory main and fuel pump relays. The harness comes pre-pinned to plug into your OEM fuel pump connector so the pump is controlled just like stock while the new mil-spec 14 awg wire takes the load. Uses factory connectors and mounting points and includes a 25A fuse.

This kit was originally designed by our friends at Trackspeed Engineering, since they're no longer producing parts we've taken over production.

Fits all NA and NB Miatas.

A good idea on any car that needs enhanced reliability over decades-old components. A very, very good idea on cars that run upgraded fuel pumps.

Good reliability upgrade!

Went through two main relays in 6 months, most likely due to a clogged fuel filter and decided to install this when I replaced the filter and pump for piece of mind. Driving from Seattle to Phoenix in a month and this is fairly cheap insurance, but I will be taking another relay just in case. Install is easy if you're comfortable with wiring, but even if you aren't this isn't that hard.

Great part for helping out the fuel system

The kit was well made and no problems with design. Real easy to install most of the time taken was removing the sheet metal backing other then that probably about a 30 min job and easy straight forward instructions would recommend

Awesome product

I ordered this product late one night and I received it less than 48 hours later, and I live in Hawaii! I was able to install the fuel pump relay and the associated wiring in about an hour as the instructions are well written and easy to follow. I highly recommend this assembly because even if you replace your stock relay, nothing guarantees it won't let you down (again) in the future, except taking the stock relay wiring out of the equation with Flyin' Miata's relay kit.
