Honda Rubicon ECM wiring help


Recommended Posts

Hello from NC ladies and gents. Been lurking here off and on and don't think I have ever posted up.

I have a 2009 Honda Rubicon. I was having a shifting problem with the Hondamatic. Determined it to be a loose connection on the gray 21 pin connector at the control unit (ECM/PCM). I located a source for the connector and replaced it. This improved the connectors feel greatly, HOWEVER, even though I thought I was careful transferring the wires/pins from the old connector to the new connector, I must have crossed up a couple wires because now the gear position display (switch is new) no longer works. It worked fine before the connector change.

No matter where I have looked, I cannot find a "pin out" for the ECM connectors. The factory service manual does not show it and I have a connection at a dealer and their service techs don't have the pin out either! I was a Chrysler/Plymouth/ Dodge tech in another life and cant imagine th factory not providing pin out diagrams for diagnostics!

I am at a loss unless I either replace the harness, OR find someone that can take multiple photos of the wires going into the gray connector so I can compare mine.

Any help or advice would be appreciated. I will also post up the location I found the connectors if that is allowed, since it seems that they fail with some age.

      Hello,
      I have read many forum topics on this matter but have never found a similar problem. So i bought a cheap ass quad thats got all sorts of parts on it. It's a 1997(if you look the date on frame) Kawasaki KLF(Bayou) 300 EUROPEAN Model (atleast I think, since I'm from Europe), the engine is 1988 if I'm not mistaken and the CDI is 1995.-2006. ( 21119-1447, 6pin ). My problem is that I don't have spark. I would diagnose the issue but connectors from CDI to wiring harness have almost all different colors and I'm not sure if they are connected correctly (pictures below). Pickup coil is putting out around 400 ohms and is pulsing. CDI is being fed 12v by one y/r wire that is coming to connector and with 12v to one gray wire which is coming from ignition switch ( quad actually doesn't have ignition switch so I'm not sure if gray should be supplying power or not). Stator looks good cause when crancking all three yellow wires put out around 5v AC. Neutral light is also on which means the switch should be ok, if it even matters. I know it's not the ignition coil since I get no power nor any kind of pulsing to G/W wire that is coming to it ( and I even put another one on there just to check an it ended with the same result). I'm nowhere near proffesional around this type of stuff so any help would be amazing.

      So this’ll be long I’ll give all the background first to see my issue skip to the ***
      Hey I picked up a pit bike and a foreman for 800 the pit bike was running but the foreman was locked up.  Sold the pit bike but when I took the top end off the piston I only found half a piston left.  So knowing the rest of the piston was down in the crankcase I knew it had to be pulled and gone thru completely.
      to pull the motor I went ahead and pulled the rear end off and unbolted the front diff to pull the drive shafts and pull the motor.  Now I have the motor torn down completely and have all the parts of the piston removed.  I know the rod and crankshaft is shot (heat discoloration and too much up and down play rod to crankshaft).  
       
      ***so I’m wondering while I have the motor apart what should I check for?  I know this motor died from heat as the oil in the head smelled like popcorn.  So what should I check to make sure I fix the issue (overheating I assume) and not just the symptoms (blown up motor lol).
      so put simply I don’t want to just rebuild the motor to have it overheat and repeat the process after 5mins of running
      Here’s some pics

      I have a problem with my 1986 honda 200sx. It idles good, but for some reason ittle start revving high. It also drives by itslef when it does that. It also wastes a lot if gas, but im more worried about the iding issue. I have the idle low right now so it wouldnt do that, but when i fix the idle, it idles good, but itll start revving up. Please help me

      My quad runs,  it starts up runs for about 10 minutes and then it dies if you let it sit for 10 minutes it’ll start back up ride for another 10 minutes and then die again, trying to figure out why it keeps stalling
