does it matter which resistor box i use to use dsm 450cc injector on my 95 civic ex?? can i use resistor box from dsm or crx or any sort??

also, what's the difference between black top vs. blue top for dsm injectors??

 

nebody??

 

you can use either resistor box. black tops are 2g DSM injectors, blue are 1g. I believe the spray pattern is slightly different but they both get the job done.
