Real Eaton Fuller for Euro Truck 18 speed permanent mod for Logitech shifter

thingiverse

This is a DIY project. The goal is to build a Real Eaton Fuller shifter based in a low-cost Logitech shifter (G25, G27, G29 about 30€ in second hand market), with NO ANNOYING CABLES. Keep in mind, this is for permanent installation and a modification with a Real Pneumatic Eaton Fuller stick, it is not a toy; it´s a real pneumatic shifter knob.

Steps: - Open Eaton Fuller and install (glued) the micro switches with 2 cables normally open when the sticks are down and back. - Optionally you can drill and install one press button (for air brakes or retarder). - All connections will be done with 3 wires and one common wire, to one JST female connector. - Pass the rest of the cable through the shifter, getting hide all of then. - The cable will enter side by side the original cable. If your cable has enough cores you could remove original one (rewiring) or left both side by side. - In order to put the cable inside you must open the shifter and drill a small hole to pass through the lower side to, leader dust protection and al last Eaton Fuller. - Separate the cone-Base of the Eaton Fuller. Drill the holes (2mm) to screw to the adapter. - Print the adapter and put it inside the Eaton Fuller cone base. - Then pass the cable (only four wires) through the leader dust protection of the shifter, the printed adapter inside the cone and then put the male JST 4 wires. - Screw it (cone and adapter) to the shifter stick. - Connect male and female connections. - Test with multi meter, each switches and later reassemble the Eaton Fuller head and screw it to cone. - Build and wire the Arduino adapter; If you are using a G25 oy G27 you can wire the Eaton Fuller installed switches to and any existing buttons. In this way no Arduino or zero delay boards will be needed. - Test it in PC. Carlos Plaza Aguilera
