Ratco is making the plug and play harness, I’m the designer and manufacturer of the manifold and the system in general. I’ve been building and selling these as DIY kits for years now via word of mouth as mentioned above. 100 % brand new aluminum construction using cnc waterjet flanges, 6061 alloy, tig welded etc.
They’ve been used in stock cars, full blown race cars and everything in between. The US, Canada, Australia, New Zealand, England etc.
I have a robust instruction set and it boils down to.
1) bolt on the manifold
2) connect the labeled wires to the sensors, power and fuel pump
3) plumb in the fuel pump
4) follow the instructions videos I include for the setup on your laptop
5) turn on the auto learn and drive.
