Yo electric gurus, please let me know if I'm missing something. I'm going single and hacked up teh harness and now checking continuity before I stick it back in. I'm having trouble with the injectors. According to this diagram, signal wires on the injectors are LG/R, LG/B, LG/W, and LG. I check this to the proper pinout on the ecu plug on the other end, 4W, 4Y, 4X, and 4Z. I get continuity.

LG/R - 4W, LG/B - 4Y, LG/W - 4X, and LG - 4Z.

Here is the problem. Looks like the round all goes to B/Y which is located at 4L position on the ecu plug. If I check ground wire from inj. plug to plug, it shows continuity. This tells me no breaks up to where they all T in. However, when I chek it against the pinout on the plug, I am not getting continuity.


I'm not electrically inclined and don't want to tear the harness apart before I know for sure. Am I suppose to get continuity from the 4L position of the ecu pin to the ground side of the injector connectors?


Thanks.

 

well your missing the rest of the diagram but from what i can tell yes you will get continuity with the key in the on position and battery connected to power the "EGI main relay" in section B-1a i dont have the rest of that wiring PDF in front of me to verify that though. so you need to track down to where that wire actually goes before it gets back to L4 at the ECU plug.

first off that B/Y isn't ground.

POWER is the same for all injectors...ECU gnds to fire them.

Look on B-1a to see where power is coming from, most likely a relay as stated.

 

thats what i was looking for i know it fired ground that page of the wiring didt verifie which side it was but ya just continue to follow that wire to check "continuity"

Found it. I didn't cut the wrong wires. Whoa.....
