question about my DSM 450s
 
i bought some 450 dsm injectors on ebay. I am in the process of installing them and the harness dont snap in to eachother. So im going to have to cut wires. The wires arent the same color. Does anyone know what color has to go to what? my DSM's have a yellow and black stripe wire and a black and blue stripe wire. My 98 honda prelude has a yellow wire and a yellow wire with black stripe. what do i do?

On the DSM clips, the yellow/black stripe wire goes to your resistor box. The other wires go to your ECU.

resistor box? I didnt think preludes had that. I was told that you just take the old ones out and put the new ones in. I figured i might have to splice some wires. but didnt know i would have to mess with the ECU

Hrm, well, from what I understand, since your car doesn't have a resistor box, you will need one. That, or inline 10w 10ohm resistors on each injector..

Re:question about my DSM 450s
 
i've heard of some dsm just connecting right in to some hondas harness. I spliced the wires put them back together the way they would be in the stock honda harness and put them in the DSM harness. So its just like using the stock harness from a honda. I havnt heard about putting in resistors if you have the wiring already and know where it goes. Im gonna try it if it starts it should idle like its running RICH... if not it shouldnt start at all... correct?
I hope im not going to hurt anything. Im not going to drive it

Re:question about my DSM 450s
 
It started right up, idle like hell. Smoked like crazy. which means it ran rich. Now i gotta hook up my SAFC and get to the exhaust shop. if anyone cares.
haha

Thanks for the help

if you're running peak and hold injectors on a saturated system then something is going to break.

if your prelude doesn't have a resistor box; INSTALL THEM!

Ya, Comp is right.

Like I said, you need to install the resistor box or inline resistors if your vehicle doesn't have the box. Your'e going to damage your injectors.

Yes, listen to the wise men. You're going to ---- something up. There is a reason people use the resistor boxes. If your Prelude was a few years older it wouldn't need the resistors, but since it isn't, you do. :P

Re:question about my DSM 450s
 
yea i need something. I turned the AFC all way to -50 and it still idled low and almost stalled when i gave it gas. Where do i get inline resistors and how much are they? this sucks i really wanted to be done!

They are pretty cheap on egay, look for some

Re:question about my DSM 450s
 
ok i seen how to hook up a resistor box... how do you do inline resistors?

Re:question about my DSM 450s
 
Jeff did a write up on DSM injector installs with inline resistors. https://www.homemadeturbo.com/tech_p...ors/index.html
I like the OEM resistor boxes better then the inline, I was going to try the inline resistors last time but I have so many OEM resistor boxes and its really eazy.
PS. if you need a Oem resistor box just PM me ill give you one just pay for shipping.

Re:question about my DSM 450s
 
I think im going to try the in line resistor. Thanks alot for the offer on the resistor box. I seen that write up with injectors. They show the person modifying the injectors and fuel rail. Mine dropped right in. Is that wrong? was i supposed to do that? because i started it and there wasnt any leaks of fuel.

Re:question about my DSM 450s
 
If it's not leaking then ---- it. It's fine. ;)

sweet thanks for the replies. Sorry for the double posts. I was in a hurry at the time.

Re:question about my DSM 450s
 
maybe they didnt snap right into the honda clips cuz remember.....you have you snip off a little peice of the 450's for them to fit the honda injector clip correctly. it can easily be done a razor blade or even file down the little plastic part of the 450 inj. to fit correctly....just a suggestion
