Here's what I would like to see.
The cable that comes out of each head could terminate with a male modular connector at a length of no more than 24 to 48 centimeters (2 to 4 feet). These male modular connectors would simply plug into female modular connectors at the ends of the long cables. The other ends of the long cables would connect to the cpu with male modular connectors (just as they do now).
Why is this a possible design improvement over current single length long cables that come out of the heads and terminate with male connectors at the cpu?
Because if the heads ever have to be removed for replacment or upgrade, you would simply unplug the male modular plug (at the end of the short length of cable running from the head) from the female modular plug at the end of the long cable that's located just inside the engine compartment of the car.
Currently you have to disconnect the male connectors from the cpu in the cabin of the car in order to remove the heads (the only other choice is to cut the cables. Not a good idea unless you have the right crimp tool AND know what you are doing).
Of course to unplug the heads you first have to get to the cpu box (in my car it is hidden above a panel under the dash) and then once you unplug the modular connectors plugs from the cpu, you have to pull them and the cable through the firewall.
Then to reconnect the heads, you have to run the plugs and the cables back through the firewall again and reconnect to the cpu. Believe me.. it's no fun to have to do this multiple times!
What do you think of the "short cables" connected to the "long cables" idea guys?
