Help please

Hi , anyone that coulp tell me what this part is call, thank you

 

…the firewall?

Or the hose clamp?

 

The black zigzag hose

 

Like the whole assembly because i believe it runs all the way on the back of the engine

 

I can't help with that but I'm curious why your brake fluid is blue.

 

Hehe thats just a pic i got from the internet
But good question

 

Some brake fluid is blue, they use dye to help you know when you're done bleeding brakes. Also comes in yellow.

That's the wiring harness I believe. Goes from the motor into the firewall and into the glove box.

 

There should be four hoses going into the firewall, one takes antifreeze into the heater core and a return, the other two also go into the heater, the smaller is the cold line and the bigger is the hot side. The antifreeze ones are made out of rubber most of the time.

 

You're right. On the other link you posted about 4WD conversion he shows that tube. It's the wiring harness.

 

I like this, hows the old 4.7 holding up?? I hear that’s a rock freaking solid engine.

 

Wiring harness going to the ECU inside the dash. Lots of wires inside there.

 

Mine is still kicking ass

 

Same here. She is super quiet with tons of pep still in this engine. With engine on and hood up she sounds like a precision machine.

 

Others have already ID'd it and are correct: Engine Wire Harness. Goes into the cabin and connects to the Engine ECU. The one on the other side, by the Master Cylinder Booster is the Engine Room Main Wire Harness. It feeds pretty much everything else in the front besides the engine: lights, horn, ABS, Main Fuse/Relay Box, horns,... It has only a grommet and no nuts or bolts holding it to the firewall. Hood cable runs through that grommet.
