Had a boosted D runnin precision 780cc peak and hold injectors, so i had a resistor box hooked up. Im now running a stock OBD2 LS (B18B) with stock injectors, so i need to get rid of the resistor box. From what i was told, the should be 5 wires coming out of the box, one main wire and 4 smaller wires going to each injector. I was told that the one wire was to be spliced into the 4 smaller wires to bypass the box, but from what i can tell, its already done, maybe i misunderstood what needs to be done. The one main wire by itself is already tied into 4 small wires which go into a pin connector that goes into the harness. Then the 4 wires that come out of the box, go to the injectors. Anybody know what wires to cut and splice??? Ive included a picture if it helps.

 

Remove resistor box. Re-attached existing wires....match the colors.

 

Thank you very much!!

 

That did not fix the problem. Car still wont start, now im throwing a code 16 for fuel injectors. And im also getting a relay clicking when i remove the plug that goes into the pin connector. When its plugged in, i can hear a faint whistle noise coming from under the dash near the ECU. Really need this figured out!!

 

all you do it take all the yellow and black wires and put tham all in the "dead" plug instead of going to the resistor box

 

Thats exactly what i did. Now im throwing a code i never had before. And i have a relay clicking somewhere that wasnt making noise before. Something is ****ed up. Problem is i didnt have much wire to work with, i might have to go to the junkyard and just cut another "dead plug" off another harness and redo it with more wire so everything can be soldered like it should be. Is it possible i have a bad connection? Or is there a bigger problem?

 

Also, im using OBD2 injectors in an OBD1 harness, if that could be causing my issue.

 

Looks like a hack job anyways. Take all the wires going to the resistor box and tie them all together.

 

How many times do i have to say it, I have already tied them together like they should be, something is messed up. Im just gonna redo it all and see what happens.

 

Redo it and report back. It isn't that difficult. Do you have your injector wires correct?

 

I dont know, none of my shop manuals give me wiring diagrams for this, so im pretty much just guessing. Ive redone it numerous times and ive also went to a junkyard and got a new dead plug and wired that in, still nothing. Im not the one who wired in the resistors in the first place, so ofcourse it is a total hack job.

Also, if you notice, there are 8 wires going into the dead plug, all yel/blk. 4 of them are a more pale looking yellow color. 7 out of 8 of the wires basically go the same direction routed through my harness, then one of the wires goes the complete opposite way in the harness. Is this a problem as well or is that right?

Im thinkin its probably going to be easier if i just go get another harness.

 

this happend to me before, i dont remember how i fixed it but lots of trial and error

 

Yea, i kinda figured. I got a new harnes but that has to have wiring done as well. If this does not work, ill have to buy a new one. I hate wiring and im not towing my car to a shop and get charged $200 to have this fixed.

Buy the ETM and it has what you need. Don't get the Haynes or Chilton or what ever. Buy the OEM one.

 

Wow, i feel like a jackass. The pin connectors for cylinder 3 and 4 injectors were flipped around. Its all good now.
