4 Red/Black wires one Yellow/black wire. Do I cut the wires going into my injectors wire one to the resistor box then have the other 4 wires going to the new 450CCs?

 

Yes and the yellow/black goes to your ignition signal.

 

But there is only 5 wires in the resistor box? So that'd be 1 coming from injector harness, 1 to ignition signal then only 3 for injectors? argh

 

does any one here have that littel diagram that showed how to wire it up there was even a picture where some one used 4 inline 10 ohm resistors if u didnt have the box. well ihave the box and need to use it. some one here has to have the diagram oif which wires go where.

Red/blacks to injectors
yellow/black to ignition

 

thats a great thread. but i still can not see clearly what wires go where and such. i saw a coor diagram on here a while ago maybe some one can clear things up a little bit more. those pictures help alot but i am still confused as to what goes where u know

Damn DC, you beat me too it.

Nextel,
It really doesn't get any more intuative than what I posted.

I think I'm going to ditch the resistor box and just go with 4 resistors. Cause I understand the 4 resistor picture lol :-X I'm such a newb with wiring

 

Heres a brief description of how I did it and Ill have pictures up tomorrow night when I get back to the shop with the camera. (Im going to make an official OBD2 install thread that is much more detailed tomorrow).

This is for a 96 civic ex with OBD2 B18C1 in it using the 96 civic ex wiring harness:

You have to use OBD1 clips (92-95 civic, 90-93 dsm, autozone obd1 gm clips)
- I used 1g DSM clips

Cut off each one of your plugs and soder in the new plugs. Easiest way to remember the wires is that with the plug on the 450cc injector (installed), the wire to the RIGHT will be sodered to a black wire on the resistor box and the LEFT wire will be sodered into the SOLID wire you just cut the clip off of. This will leave the HARNESS end of the yellow/black wire hanging. Once you soder the four RIGHT wires to each black wire from the resistor box and the four LEFT wires to the solid wires from each left over clip wires, THEN soder the 4 remaining dangling yellow/black wires all to the ONE red wire out of the resistor box. This puts the resistor box IN LINE with the harness.

EDIT: I now notice your box was like mine (included the harness connectors so you are really connecting wires to 4 red and one yellow/black. Just subsitute the colors in my previous paragraph... four red wires from resistor box = four black wires from resistor box PLUG (green plug). one red wire from resistor box = one yellow/black wire from resistor box PLUG.

Like I said. Ill have pictures tomorrow.

EDIT 2: Here is my rendition of my wiring... I dont have the DSM clip wire colors memorized so they are just blue. NOTE that on dsm clip wires, the RIGHT wires are not all yellow/black. I just did that to resemble Honda wire colors.

I think I'm gonna go with 4 resistors, too..

 

each inj will have 1 wire that is the same on each...cut each of those and tie them together and run them to the 1 wire that is different on the resistorbox. then take each of the remaining wires on the resistorbox that are identical and run each one to the clipped wire on each injector. really simple and much better than individual resistors.

 

This is the stock wiring configuration.


This is the modified wiring configuration.


The resistor box has internal to it 4 resistors with one lead of each tied together. This common lead gets tied to a switched ignition source, such as the original power wire (blk/yel) at the junction connector. The junction connector is partially displayed in the first picture.

Notice in the first picture that each injector has a blk/yel power wire feeding it. You need to cut EACH blk/yel wire and solder one of the remaining 4 wires from the resistor box. It does not matter which wire...they are just resistors which are all tied to +V.

i'm with ya there man . . . mine only has 5 wire's . . . . I believe those are the one's from the accords, so how do we wire the resistor boxes that only have 5 wire's coming from them?

ah ok i think i get it know. form teh pictures it shows each injector has 2 wires. 1 is yellow/black (power) and the other is a certain color that goes to the ecu. so basically we onlt cut the yellow/black wires at the injector and the yelow/black wire coming from teh injector goes inot the resistro box and the coored wire that goes to the ecu we leave alone. so basically all we are doing is splicing the resistro box inbetween the injecotr power source and the injector itself. sort of just liek placing a resistor right in between the injector and power distribution block. am i right?

 

ok well i went out and looked at my power distribution block (the one with seven yellow and black wires and has a plastic cap) and was just tryin to figure out what wire went to what without a voltmeter and i noticed there are only seven yellow and black wires. but i looked closr and noticed 4 of the wires were dark yellow and black and the other 3 were light yellow and black so i guess the 4 dark yellow and black wires go to the 4 injectors and the 3 light yellow and black wires are teh power wires. am i right?

 

my resistor box has 5 wire's total. I believe it's 4 black wire's, and one red wire. The 4 Black wire's are ran into the injectors, and the 1 Red wire is ran to a 12v power source that turns on when the car turns on . . . . is that correct?

Can someone clerify for me exactly what wire's I need to cut from the harness, or the injectors? Got finish up my install today with my buddy. my car has been down for a week now. Any help is greatly appreciated.

Yes to the first paragraph. If this is an OBD1 car, the distribution block you need is on the drivers side just where they say here:
http://www.hondata.com/techinjectorwiring.html

Now since my was different than the link above as far as what wires, you will need to check continuity to see which wires you need. You will need a voltmeter that tests continuity first. Then unhook all injector clips Hook 1 wire of the voltmeter to the yellow and black wire of the injector clip. (you may have to have someone hold it there). Next, hook the other wire from the voltmeter to a wire in the distribution block marked in the Hondata site. When it beeps (my voltmeter beeps but yours may do something else like take a **** for all i know. ) this is the wire you need to solder too. Mark it with a marker. Repeat 3 more times.

Done

 

Where does the red wire that is left tie into the 12v power source? WHat wire would be of sufficient voltage to power the resistor box, or to make it function properly?

For anyone interested, the RadioShack part number is 271-132. I paid $1.69 for 2.

 

That's one blurry picture. Now you all got me confused lol. **** my resistor box got 5 black wires and 1 red wire.

Get someone else to do it then. It is a piece of cake to do.

 

What other cars can you use injector boxes off?....or can you only use the resistor box off 90-91 civic si?
