ok i installed the dsm 450cc injectors in , now i am doing the wiring
from the Resistor box there 4 black wires and they are supposed to
be wired to each yellow/black wires on the injector. correct ?
now my question is where does the Red wire connect to ?

here are some pics of the wiring



where does this connect to ? red wire

anyone know
?

the red wire on the resistor box goes to the other end of the yellow/black wire going to the ecu.....some people say to use only one....but i hooked up all 4 to the one red wire

Do you need a resistor box in order to run DSM 450s? because im about to install mine once i get my fuel pump and i would like to know. If so where do i get them from? (what car)

You don't need a resistor box, but you do need to put 10 watt 10 ohm resistors inline with the injectors.



I stole that pic and info from

ok guys , just talked to a buddy of mines and he told me this...
yellow/black wires go to the black wires on the res. box

the red wire from the box , i can run 4 wires from the red one
to each color on the injector ... like run a red to the blue, red to yellow , red to brown , red to red on the injectors

is this correct?

This sounds right

i see that i have to wire the rest to the 4 other wires
but on mines i am missing one

i dont have that thing to test to see which ones go to the injectors , and the others to the red wire
thats why i am wondering if i can just run a red wire to each color on the injector to make it work

bump i whould like to know also

okay guyz how hard is it to get the injectors into the fuel rail I heard u had to drill something out.

GReddy SI

u might have to sand the inside of the O ring a bit for your injectors to fit right in

oh crap it
is this the right number for the
10 ohm 10W 5% Wirewound Resistor pk/2

this the right ones i need

Man you guys are making this way to hard. The red wire needs to be wired to a 12volt switched source on the engine harness. Tap it into something. Then the 4 black wires go to the yellow and black of each injector. One per wire. Bam your done. Power is sent thru the red wire thru the box which ads resistance to the black wires and into the injectors. Hope that helps.

yea you have to bore out the inside of the O-rings. im doing it now and its more of a pain in the *** than i thought, but still not too bad. im finding that i need to take out more material then i thought i would...

Let me see if I can explain it so you guys understand it. There should be 5 wires coming out of the resistor box. All of mine were the same color I believe. First, go to the injector and find the yellow/black wires. Cut them, but make sure that the wires will reach the resistor box. You need to solder 1 of each of the yellow/black wires that are coming from the injector to 1 of each of the 4 wires off the resistor box that are the same color. Then you need to wire the other side of the yellow/black wires that are coming from the wire harness now to the remaining wire. All 4 coming from the wiring harness get soldered to this one wire. It is pretty easy once you understand it. Took me a little bit to understand but I got it.

well i connected and it started up
but it runs really bad like if i am running on 3 cycl
what can be wrong ?
how can i check if the injectors work
?

the resistor box just goes inline with the yellow/black ground wires. 4 go in through the 4 same color wires on the box, 4 go out through the one big *** wire on the box. thats all
