i just want to make sure that i have this all right in my head before i do it. when installing 450's if i have a resistor box, i leave the yellow an black wire alone, splice the other wires into the resistor box, and splice the resistor box red wire into a 12v power source, i have read through the articles on it, and want to make sure i have it straight. thanks.

Hondata's wiring info is really good. Did all my wiring using just their diagrams.

 

the resistor box im using has 4 red wires and one yellow, im assuming that the yellow is the power, does that make sense?

 

very much... the way i hooked mine up is i took 2 of the old injector wiring and twisted those together, then hooked that up to the yellow wire on the resistor box then ran the red ones to each injector in any order. works great.

 

so you only connected 2 of the wires, and there are 2 that dont connect to anything from the power source?
