rewiring is easy to do on our cars
at the fuel rail you have a big connector which connect the 4 injectors to the main harness
you have 5 wires 1 is the common incomming 12v the 4 others are the injectors driver near the big plug cut the 4 wires and soldered them back with heat shrink carefull you have to see it from the computer point of view because you could do a mistake and do 1 on 4 , 4 on 3 etc
so wire from computer channel 1 soldered to wire going to injector 2 wire from computer channel 2 soldered to wire going to injector 3 wire from computer channel 3 soldered to wire going to injector 4 wire from computer channel 4 soldered to wire going to injector 1
recap of why we have to do this 2.0 either 420a or neon are timmed on cylinder 1 2.4 have balancing shaft because of that they put the crank sensor on cylinder 2 the cam sensor have the magnet at a different angle and the 2.4 computer knows all that but US we need to make our computer think that cylinder 2 is cylinder 1 for fire and fuel 1/2 turn of crank = 1/4 turn of cam so if the crank is 180 off we turn the cam sensor magnet 90 degres off clockwise and they are now in sync the computer is happy and want to send fuel and fire on cylinder 1 and 4 but we need to send that to cylinder 2 and 3 that the job of the injector and coil pack rewiring
