Harness routing on S5 Tiis

As you may recall, we couldnt get our newly rebuilt and swapped in JDM S5 Tii running well so I've pretty much removed all of the intake system except the LIM (I dont think you can remove that without removing the turbo/exhaust manifold).

I dont think I have the harness routed correctly as there seems to be a huge choke point at the LIM, air pump, etc. While I have the intake all off, seemed like a good time to revisit the routing.

It is a now modified NA harness on a JDM Tii running N370 sensors, etc. The mods are just for the two Tii specific solenoids.

I've used this thread as a reference but it seems that no matter what that the harness is going to interfere with the two sensors in the back of the water pump.

I've attached pictures. This first one is an overview shot to set context. You can see the harness running atop the front iron starting at the CAS.

This is a close up shot of the area in question. The silver lines are the vacuum hoses on the rats nest. You can see that I have the harness going under the two sensors but the black one is basically pinched in there.

This picture is from the driver's side. You can see how the black sensor's wire has to bend.

Any guidance?

thanks,

Should not that large harness be routed Above the sensors? I don't own a series five, but I think it goes above the water thermosensor.

Above huh? There was a post in that thread I referenced that said the harness went along the thermostat housing neck. There is a molded in bracket of sorts near where the radiator hose attaches. I ran the BAC waterline thru that.

I'll have to see if the harness would go in there.

Thanks, Hailers.

Seems someone with a series five could maybe pipe in and help out on this.

The jpg attached is not my car. I stole the thing off this site. You can see he routed .....where it's routed. I don't KNOW that is right or wrong.

Pay no attention to words on the jpg. They are there for another reason.

Help save the polar bears so they can kill again! Of course these cute, cuddly bears wouldn't do this to us.

Ah, folks are probably just getting ready to winterize their cars and planning their winter projects (those of us in TX excluded of course! ).

I think I'll try it. i'm not sure this guys routing is "right" since it is obvious the harness has been "dealt with harshly". Either way, I think getting the harness up will be a good thing anyway because it is really crammed in there where it goes between the turbo output pipe and the LIM and air pump hoses. I'd just assumed they'd routed it to be out of sight.

Thanks!

Jim

The fourth picture is of an FC with a failed pulsation damper, right?

I have my harness routed across the front of the engine behind the ALT. Then around the solenoid rack along the rear fuel line to the primary fuel rail. That may or may not be the right way to route it though. Thats just what works for me.

Yeah, that's how I have mine. My question was how does it go from on top of the front iron from the ALT to the passenger side wheel well?

I have it held down with a bracket on the pass side wheel well then over in front of the LIM and behind the ALT.

Do you have the harness passing thru the molded in bracket on the back of the thermostat housing?

It's really a F111C of the RAAF dumping fuel, and lighting it up by going to AB. F111's carried approx 32-33,000 lbs of fuel and have/had a fuel dump duct at the rear end of the airplane b/t the two engines exhaust.

Say you took off and had a problem and had to land. You don't want to land heavy (50,000lb airframe plus 33,000 lbs of fuel adds up), so they dump the excess fuel and land without having tire/brake problems on landing. That's a travel pod on the left wing. They carry their golf clubs and swimming fins from one site to the other with it. humor

The polar bear picture is to put all the goofy *save the polar bears* propaganda, into perspective. I say kill 'em all.

Oh, I thought the polar bear picture was of an FC owner who went to the dealership for service. The technician being the red gooey blob on the left!
