Crazy blue unplugged wires

Anyone know what these unplugged blue connections are? Driving me nuts trying to figure out what they go to. Any help would be great!

crazy blue wires

I don't know where to find codes on the wires. But here are two more pics that should show them better. Thanks for help!

Maybe they go into whatever attaches to the mounting plate you took pictures of.

I see you don't have AC. I think they're the pigtails for the compressor.

Taken from my '99 4.0.

On top of the compressor



Just under it, to the front



Another view, taken from the front



They come out of this harness



There are four connections. Two to the AC compressor (shown to the right), one to the solenoid (pointer) and I think the last one to/from the alternator.

Not a great pic and I couldn't my "pointer" down there, but there's a wire that plugs into the back of the alternator. This one meets up with this one

[/QUOTE]

And they loop in front of the battery then go into the firewall.

I would think, however, if these aren't connected you'd have some noticeable problems.

Hope it helps.

Wordgie, Thanks for the info. I think from your pics that the AC compresor is mounted on top of the alternator bracket. That would definetly explain the two up front. I failed to mention that its the 2.5 powerplant. Is there any chance that the two blue connections coming from the fire wall behind the battery are for the unused factory foglights?

Indy, I think you are right. From Wordgie's pics that plate looks like where the AC compressor would go.

Yeah, the bracket is for the AC. I was taking my pics when you posted that so I didn't get a chance to address it. My thinking is, those wires are for the AC. Did yours originally have AC or did the PO ditch it?

I'm not thinking fog lights since mine didn't have the lights or the pigtail under there.

Look under the bracket and to the back of the alternator just to make sure that pigtail is there. Like I said, it should be there or you'd have other issues like it not starting.

pigtail

Thanks agin Wordgie I believe you are correct on all accounts. And no it did not come with AC. When I get off duty today Ill crawl under the alternator and look. I'm just going to ziptie these unused ones to keep them out of the way. The one up front is long enough to get into the serpentine belt. Thanks again!

It's for A/C. It's cheaper to use one general wiring harness for all model trims options. It's this way with every car manufacturer.
