Hello , manufacturer of blinder , I could send you a direct email but I liked to see what others think of it .
Overall on the m-20 the wiring is well done and quite easy to figure out.
But the difficulty arises from having to run the 2 wires from the interface to the transponders.
1 ) Why not be able to send the ''conversation'' between the interface and the transponders via a wireless link.This way the transponders could be hot wired to the -+ close to their location.
This link could be optional , just plugging it to the interface and , voila !
2)Even easier would be to have the interface under the hood with a proven heatshield /weatherproof and receiving the alert in the cabin via a wireless link.The receiver could then be on battery and/or 12 volts.
3)Stealthiness is always compromised by suspicious wires , and arrived an age where it becomes uneasy to play the contortionist under the dash, unless one is a due member of Cirque du Soleil.
2 ) in the meantime , can i use a doubler on the interface , so i could only run one wire instead of two , this way i could double the feeder to deliver the signal to each transponder.
3) If my idea find a way , can i received this option free as an appreciation? ah ah
