Can I run wires straight from the sensors (ex. vtec selnoid) to the ecu and bypass the cannon plugs that leads to the cabin (dont know if im explaining myself right) it just seems im a bit confusing where i would plug the wires from the sensors to the cannon plugs and then out of there to the firewall.

my fiances uncle is going to help me install either a d16z6 or a d15b and i want to take care of the important wiring like the vtec and others like 1 wire 02 sensor to 4 wire 02 because i have a cx and i need to be as knowlegable as possible when the swap is in progress i dont have much time for screw ups
But yea can i run wires straight from the sensors (ex. vtec selnoid) to the ecu .

thanks for reading
