There is a thick wire that is connected to the bottom of my air filter encasement, and I have never seen it hanging down before. It's orange, and has a 3 holes at the end. I can't seem to see where it hooks up. I noticed it after a really bad day of offroading. Anyone know where it might hook up?? Thanks.

 

Oh come on, someone must know what im talking about. I'll look at it tomorrow and see if i can get some more specific info about it. I'll also run the scanner and see if it throws a code. The wire runs down to the frame, but it looks only like 4 ft at the most in length.

 

offroadmaniac,

I looked this AM, under where the filter housing would be if it was still on mine, and could not find a thick org wire with 3 holes in the end.

can you take a picture of it ?
I saw a thick org wire in one of the connectors, but I don't think that is what you are talking about. ??

This is just a guess but if the wire is truly bolted to the frame then it's probably a ground wire for the engine.

They do ground the engine thru a seperate wire to the chassis. I am not sure if they went as far as grounding the chassis to frame.

It needs to be grounded because if the wire is not there then the ground path goes thru the wheel bearings. This cause them to heat up and causing early failure.

 

Well, i looked at it again, and it isn't really connected to the air filter housing, it just has like a hanging bracket there for it. It actually runs to in front of the radiator, but i cant see where it begins. It is a wrapped in black hosing, but near the end it is orange. It is a 4.6. I looked at my truck with the 5.4 and couldnt find it on that one.

 

I dont believe it is a ground wire, it just has a bracket on the frame.

 

A picture would help. What mods besides lift have you done. OEM there is no orange wire that I know of.

These are pics from Rocks on his 97 4.6.

Is what you are taling about in the lower right hand corner of the picture ? ( I can only hope not... )

A Bit farther away from the one above.

Note that this is a K&N FIPK, but you get a clear shot under it without the stock housing on there.

Steve,

I don't think it is that. offroadmaniac would be also complaining of a no start if it were. The "Thick" wire is a killer.

offroadmaniac ,

How thick is the wire? Is there more than one?

JMC

 

Don't think it would start on 4 cyl ?

True that would be another complaint all together ( why I said I hope not ).

Ok, this is thin - real thin.

Your truck by some long shot didn't come with a block heater did it? Sounds like the extension cord for the block heater.

Our company's F250 diesel has a block heater and the extension cord is routed out to in front of the radiator like the cord you're seeing.

Like I said, thin.

 

Yea, actually the truck does have a block heater. But, i dont think it's that type of extension. If it was, i dont think it would be heading toward the rear of the truck. I'll try and check it out again tomorrow. Thanks for helping guys.

 

Thake a picture! This is killing me. I gotta know!

JMC

 

it's killing me also, I cannot figure out for the life of me what it is. If you don't post a picture, I have to resort to posting pictures of grease fittings next, and ask if that is it

My block heater is a black 3 wire cord in a black wire loom.
The block heater ends used to look like a 3 leaf clover. I don't know if the one I currently have is that way. Mine is running along the drivers side frame, going to the engine.

PS : knocked those last inline pics down to URLs, since they were useless Sure it is running ???

 

Ok, i think i figured it out. I think it is to the block heater. I kind of eyed it to the front, and it has a plug at the end (like one you plug into an outlet). So, if that is so, where does this wire hook up, the block heater itself?? If so, i dont know where that is. I live in AZ, so its not like i need it to work. Let me know if im right about this. Thanks for your help. Oh, and sorry i cant post pics, i dont have a digi camera.
