Had a blown head gasket and paid a guy to fix it. Well that guy sucks should've done it myself. Any way the fuel injector plugs are two colored black or tan/brown I need to know which ones go to which side of the motor. The manual and wiring diagrams show which color wires go to each cylinder but for some reason the colors don't match any of my wires. Well the green wires match up but they all have them. But if you know which side the connectors go to it would help me save a lot of time. Thanks

 

Was really hoping for a little help here. The repair manual shows all 6 injector plugs as black my car has 3 black 3 brown. None of the colors in the wiring diagram match my injector harness. Could someone with the same black/brown plugs post a picture or just say which bank goes to which color please. I don't know how else to check them I don't have the magic 5 point star security bit to pull the pcm harness and trace them. Thanks .

 

The Electrical Guide for MY2005 onward is attached below.

Refer to page 63 for the colours of the wires going to each injector with the injectors numbered with reference to the diagram on the left.

 

I have that guide. That is where it says all the connectors are black. All my ground wires are green with pink stripe it says blue or something and none of the other colors do not match my wiring. I've stared at it and my car and it makes no sense

 

I think you can see the wires and plug for the front two injectors. I've swapped them but it runs both ways poorly I might add both ways have misfires and fuel trim issues

 

 

Sorry, I'm trying to understand why your particular vehicle has a different wiring loom to all other MY2005 X202s and beyond. There must be a logical explanation.

Perhaps it would be best to remove the inlet manifold and take photos of the entire area along with the wiring looms and connectors.

Sometimes going back to the beginning is the only way to solve a situation like this.

 

Could it be another MY wrongly thought to be 2005?

The VIN has the MY...

 

I purchased the vehicle with 42k miles on it. As you can see in the picture my ground wires are green with pink stripes all 6 of them are the same. Given the milage I believe they are original. I downloaded the wiring guide here. Is there another wiring guide available where the wires match my colors? I haven't seen one. My vin is:SAJWA01T95FN50612. thank you again for taking time to try and help me.

 

Thanks - yep, MY 2005.

 

Ok I'm pretty certain that the way it is in the picture is correct. Found vacuum leak causing the poor running conditions and now everything is pretty stable. So if anyone ever has this issue the black plugs go to bank 1 and the brown plugs bank 2. Next on the list...figuring out why a/c compressor 6not coming on and hot air is blowing. It's going to be a wiring issue I think. A couple of times it worked fine both times right after I had the radiator out . Not sure about the guide for help.🤞

 

More often than not, the problem is the DCCV and not the wiring. A failing DCCV can also take out the climate control unit as an this creates an excessive current draw which fries the traces on the PCB inside the unit.

 

Thanks for the pointer. That was one of the 1st things I replaced on this car and checked the climate control module out also. It was later when I replaced the radiator and the a/c condenser was loose and hanging and I put it all back that it worked. And again same circumstances it worked again. Both times only for about 10 minutes. . I have to figure it out soon though. Temps are getting over 100°f here.

 

One thing to check is the transducer at the right hand side of the condenser. Be careful though. it is on a schrader valve that only seals via an o-ring at the base. I had mine fail and the Jag dealers will try to sell you the entire aluminum piping assembly, rather than just the sensor.

If you have a refrigerant leak and the system pressure falls below a certain threshold, the control module will inhibit the engagement of the compressor clutch. One other item to check is the AC compressor relay in the engine compartment fuse box. A simple "swap out" test with another known good relay will suffice there.

 

Here you go, written just for you:

You may have more than one active fault. Use a thermometer to determine if the "hot air" is warmer, cooler, or the same as ambient.

 

In my picture it is backwards. Long term fuel trims ended up way crazy as it leaned and richened the wrong banks. And a/c update. It blows cold on the passenger side and hot on the driver's side. Guessing no power to driver's side of the dccv and default position is open closes when power to the valve.

Screen shot of you tube video. If you zoom in you can see the brown plugs. (According to the wiring guide they are all black) bet his grounds are green w/pink stripes too. I think the guide is wrong on all of it. The repair manual has problems too. Setting the timing and follow the guide. At end to check if correct the marks on intake cam heads are different. Doesn't say "damvb" on backs of mine just a rectangular depression. And only one side lined up not both.
