IS this a botched connector or what, near the trans, looks like a PCM connector

Crown Vic Owner · #1 (**permalink**) 12-26-07, 08:55 AM

Almost, i dont know for sure, i think this is odd, it looks almost like one of those make a connector connectors. Its on the right side of the coolant tank in that area.

rofl
not a pcm connector
it is however a max connector
why do you ask?

Crown Vic Owner · #3 (**permalink**) 12-26-07, 12:44 PM

dont laugh, i honestly dont know what its for.
I got curious after all the BS with this car.

Its just that the connector looks homemade for some reason.

I will look at my 99 if I can get it back from the wife after I finish changing the alternator in her Concorde. PITA

I would bet that is factory but somebody gooned up the backshell/cover.

I have the same hacked up looking POS on my fenderwell. Double sided with wires hanging out. No idea what it does but I hope its not important.

If I'm looking at the photo correctly I would say it's the main connector between the body harness which goes through the firewall and the engine harness. There should be a bracket attached to the drivers side strut tower to support it. If that's it, it is very important.

Weephee is right, its very important, heres what it contains; C101

Nice to see that when they produced a $54,000 car in 1999 they skipped a $5 backshell for this connector, or even 50 cents of electical tape and wire loom.

ewill3rd · #9 (**permalink**) 12-27-07, 09:16 AM

That is C101 alright. It may not be pretty but it works just fine.
I think that is a Packard Electric connector, it doesn't look like much but it is what I refer to as a "weatherpack" connection. It has a seal on each wire to prevent water intrusion. There is a lock on it to hold the connection tight and honestly we rarely have trouble with it.
The picture shows it dangling in the air, it should be hooked on a bracket or clip on the side of the strut tower, that might make it look cleaner and you can always kind of squeeeze all the wires together and wrap some electrical tape around the harness to make it look nicer.
It looks like someone has been messing with it, what kind of work has been done on this car?

submariner409 · #10 (**permalink**) 12-27-07, 09:50 AM

Crown Vic's car is the one with the "reman" strange engine with strange lineage, with strange symptoms which never seems to run correctly. I think his Dad or an associate did the job and it apparently hasn't been right since.

Gearheaad43 · #11 (**permalink**) 12-27-07, 02:54 PM

Geez I was thinking there should be some kind of weather pak on the backside of that C101!!!

eWill3rd, did you happen to read that post about the new dude with s '93 Deville that has a werido problem of stalling every time he turns on the HVAC????.. I'm curious as to what you think the diagnosis would be.

Crown Vic Owner · #12 (**permalink**) 12-27-07, 04:32 PM

yep, its a reman or something

who knows.

Either way i ended up securing it to the strut tower.

CadillacSTS2003 · #13 (**permalink**) 12-27-07, 06:22 PM

i didnt mean no offense man
pcm plug is huge thats way to small to be one
and i was laughin cuz it seems every other day you have an issue with that SLS

Crown Vic Owner · #14 (**permalink**) 12-27-07, 07:36 PM

quick question, how many RPMs do you turn in 4th at 60 MPH?

submariner409 · #15 (**permalink**) 12-27-07, 09:17 PM

You need to find your final drive ratio (3:11 or 3:71), because answers from several different vehicles will be meaningless unless you know which ratio they're driving. (......and the rpm will change depending on whether you're in 4th or 4th with torque converter lockup (D).) Your transmission has 4 primary speeds as well as convertor lockup for "5th" or OD.
