I'm rewiring the harness to my 73 csi euro and notice that one wire splits and goes to the number 1 and 3 fuel injectors, and same with number 2 and 4. Number 5 and 6 injectors are supplied with their own wires. That would mean that 1 and 3, and 2 and 4 would be injecting fuel at the same time. To me that doesn't make sense, or perhaps the pistons of 1 and 3 are in a close enough phase it doesn't matter when fuel gets injected. Same with number 2 and 4. Could anyone comment and advise. Thanks. Jeff
