i read all the posts on here but im still confused. so there are 8 wires in the harness that are yellow and black.......4 go to the injectors and the other 4 go where? first step is to find which one go to the injectors by checking continuity....so i find them and solder them together and connect to the black wire on the resistor box.......now im stuck.......where do the red wires in the box connect too? i need someone to break it down in stupid terms for me thanx!!!!

so the colored ones to the injectors really dont even need to be clipped then right? im using the honda clips

 

Maybe this link will be of better help.

so if i use the honda clips i dont need to splice the colored wires on the injectors?

 

You need to splice it at the connector near the shock tower.

 

not understanding why i have to splice those colored wires to the injectors

 

how much hp are dsm 450 good for?

 

ive heard max about 275-300

 

i would change the injectors to bigger ones if i were planning to make 300. Are you trying to solder it straight to the injectors or are you soldering it to the dead end?

if you are soldering it to the injectors, the 4 common wires from the harness solder to the red wire on the resistor box. The 4 common wires coming from the injector clips you wire each one of them separately to the 4black wires coming from the resistor box.

i suck at detailing.

 

damn what a mess... all you need to CUT are the ones that are yellow/black... the others NO NOTHING NADA...

if you are using a honda civic/crx 88-91 or DA resistor box..

you take the 4 yellow ones that are NOT going to the injectors and you solder them together to the SINGLE RED cable on the resistor... the other 4 BLACK cables coming from the resistor are going to the Injectors... yes through the same yellow blacks you just cutted...

So CUT the 4 yellow blacks...
so now you have 8 yellow blacks.... 4 from the harness of the car and 4 going to the injectors..

the 4 from the harness of the car u put solder them together with the lone RED from the resistor Box

the 4 BLACK coming out of the resistor box go to the remaining 4 yellow/black to the injectors...


OOHHH you made me get my leet skillz on paint for this one... i think this is as mistake proof as i can make it at 5 am.

 

good job. thats what i was trying to explain.

 

thanks guys thats alot easier to understand!
