The other day I installed some dsm blues and a resistor box... I used the DIY on here and thought that i hooked it up right but there is a solid cell and car runs/idles really weird. Pulled the code..solid. car runs but not good. Does it looked like i hooked this box up right? (I used the connector so the colors are different., and i have a pretuned ecu from pharable with the dsm's programmed)Can someone explain the dead end connector to me?

 

nobody?

 

cant really tell you if its hooked up right or not

did you find the 4 injectors wire and hook it up the resitor box?
or did you randomly pick them out

 

I checked for consistnacy of course and the wires from the injector to the plug are a darker color then the others so that makes it easy too

 

I may need a better pic, but that green connector is from the resistor box right?

Theres five wires coming out of my resistor box, i can't really tell well, cuz i have mine all hidden now, but four wires from the resistor box go to the injectors, and the other one, is suppose to go to the power wires. It looks like from the pic, you hooked up the power wires to the wrong wire in the green clip. Maybe its a bad pic, but those power wires need to be hooked to your resistor box, not that clip.

 

Heres how i have it hooked up... the 4 power wires from the injectors are soldiered to the 4 red wires on the plug which are connected to the 4 black ones on the box... then where i cut the wires on the dead end connector side those 4 are soldiered to the yellow wire which when plugged in is the red wire on the box... How do the wires get power if they are hooked up to a dead end connector? do they get power transfered through the dead end connector from the other yellow wires?? can someone enlighten me please.. thanks

 

Yes they do.

Thats confusing as all hell. Why did you leave the connector in there?

Just cut off the connector and wire it all up directly.

Typically a solid CEL is your computer, something isn't right, i believe they claim to test all there computers before they go out, so did you make any changes, trying to tune it yourself?

 

its gotts be the wiring ... i put my stock pr4 ecu in there and just turned on the ignition and same thing happened... solid cell.. no i havnt really even ran the thing since i dont have a dp right now.... i started it up and let it warm to check for oil leaks in my lines but thats it.

 

I mean it cant be the wiring.. maybe the box itself is bad?

 

did u start it up before hand? how do you know its the injectors? check to see what code its throwing

Read the first post.. its a solid cell

 

Check your wiring it's not that hard to install.

Thats how its setup

what are the chances of your pr4 ecu being fried also? maybe try your ecu in someone elses car

You deserve a medal if you managed to burn that resistor box I highly doubt it's the resistor box. Make sure that the wires you put the resistor box in series with were indeed the +12v wires and not the ecu ground wires. Sounds like you have mixed one or more of them up so triple check otherwise you could burn your ecu's!

 

I dont really get why people even bother with that resistance/continuity check crap to figure out which wire is which. I just use the simpliest and surest method, which is tapping from the injector connector itself. This install can be just as clean........

 

Ringing your wires out is the surest method. Do it.

 

Are you plugging that green plug into something?? The way you have it wired up, the power wires are doing nothing. Cut all your wires a few inches from the box. Run the four injector wires directly into the harness, and then the single wire into the dead end plug. From what i can see the power wires are just spliced to a wire in that green plug, which is doing nothing.

 

Tape only hides things....use heat shrink when you cut that unecessary connector off.

 

that little green connector connects to the plug on the resistor box... i used it to have some more room so i owuld nt have to extend the wires... it connects to the resistor box

 

the dead end connector you are referring to is a simple 'distribution' box for ignition switched 12v. There are 8 wires going into it, all of them share a common node (being 12v)

Within the harness, 12v comes from the engine harness on the driver side, and goes to the dead end plug. The 12v then gets sent to the injectors, O2 sensor, IACV, and something else.

Looking at the back of the plug with the large plastic extrusion facing to the right, if they are numbered like this:

1 5
2 6
3 7
4 8

Which pins did you snip? Here is the pinout

1 - Driver side engine harness
2 - brown wire injector (cyl 1)
3 - red wire injector (cyl 2)
4 - blue wire injector (cyl 3)
5 - yel wire injector (cyl 4)
6 - Butterfly reservoir (I think)
7 - 02 sensor
8 - IACV

Did you cut the correct wires? From the picture, its hard to tell but it looks as if you did.

 

EDIT:

Actually believe it or not you've got it hooked up like the electrical manual shows it should be.


I never looked at the electrical manual when I did mine and just rang out the wires. The way I have it is (looking into the wire side of mine) 3,5,6,7 connected to it instead of (looking into the wire side of yours) 1,2,3,8. Cause my car works fine.

I wonder if the electrical manual goofed.

Does anyone else have the electrical service manual or Haynes that have a working resistor box?

Hondata is wrong too.
So is Haynes.

In your picture try using the lighter colored wires. I've got mine hooked up to the lighter ones. Check the lighter one on pin four(in the picture the one on the right bottom corner). That should be the ign switched 12V according to the electrical manual. Otherwise the one on top of that is pin 3. Which is my other lighter colored one.

Cliffs: My lighter yellow wires - Pins: 3,5,6,7. Your lighter yellow wires - Pins: 4,5,6,7(looks like from the pics). Check your wire going to pin 4 though cause that should be ign switched 12V, not an injector wire.

Oh ya and ring the wires out(check continuity) before you start wiring.

Put the ecu in my 95 dx and same thing.. solid cell.. when i jumped it it was solid as well but the srs light was flashing?? never came across that before? Im not sure if the ecu was fried when i got it from my friend or not but i dont remember it being fried when he gave it to me.. i still have a stock pr4 ecu that i guess ill need to get chipped and a basemap put on it.. anybody know of anyone that could help me out with that?

 

In my opinion if your car will actually run, your computer is fine. I would get the chip reprogramed, making sure everything is set up right for your engine. As in knock sensors things like that, and for whatever injectors you are running.
