Damn Vbulliten I am your boss dont tell me I need more than 10char!!!

Now that the boost guage is finished.. I am starting on the fog lights. I need to get the terminals for a 56-way F amp connector. Terminals or Terminals with Pig Tails... If anyone knows of a dead ION or the such. Need the small ( believe micro-64 x 3) and the 280 series terminals. I had all the time in the world for the Boost Guage. With this, time is starting to get compressed.. Any help would be appreciated.. Thanks to WOT for his great input....

They are going into blank positions in the connectors. One is a 280 series Female and the others look like micro 64s but they are not Delphi connectors and WOT informed me they are AMP/Lear so the retainers might not work. Basically, I need the terminals and/or the terminals with a pigtail (preferred). The connector/housings PN# 1326144-1 for the black and 1326144-2 for the gray. I just need to add a couple of terminals to the above referenced connectors. I simply want to put the right terminal in the right connector.

If I'm not mistaken you will need to order the Comp Pack front grille as well??(that black platic insert where the fog lamps themselves mount)
I've never really checked it out in parts - but it must be different to be able to mount the lamps.

The MetriPac 280 terminals shouldnt be too bad Mark, just get a few from a GM dealer, or (if necc) book it in there to have THEM R&R the BCM and add the circuits. Might cost you a couple hrs labour but might extend your sanity!!

I have all of the parts in... You can delete 22685052 as they are not needed on this lamp assbly. I also have the pigtails for the lamps and for the main power junction box (under hood fuse box). When I get the install complete, I will post what I used up so there will be a fairly close parts list with expendables. I also have a 56 way from wrecked 03 for the BCM in route along with C3 from the under hood fuse box to match some sample terminals that I got from Kimball Midwest. If they match up, I will also post those numbers along with the replacement GM number. Install starts on Friday..........

Still need those pics if anyone has them or is willing to take them. PM, e-mail or post in thread......


Thanks,

Mark

Well, there is a problem.. So anyone else thinking of this hang on. The relay circuit (#317) is ALWAYS high. I am going to take it to a mod friendly dealer and take a look at the config file sometime in the next week or so. Any input from the forum would be appreciated. It is a bit strange, I can not see GM leaving a set of outputs high instead of low as not used. I wonder if it is VIN triggered....

Hey Mailmars, any update on getting the foglights working?

No pressure, just curious.

I do have a question for ya... I see your part numbers for the lamp assemblies are the same. Is there no differentiation between the right and left lamp assemblies?

Does the parts list you have so far include the inserts which go in the bumper? I don't know what name they would be referred to as... Maybe fog lamp housings? Grille inserts? I just don't know.

They would be the part that replaces the two blank grille inserts that are where the fog lights are supposed to mount.

Is that this part?

1 15223620 Grille-Rad-Lower 69.21

And again, if this is the part does it come with both the right and left lamp housings?

Thanks for any info you can provide!

Another question, or comment rather, is have you tried just installing your own relay network to the factory switch?

I would envision the factory switch having 4 wires, although I could be wrong. 2 wires for illumination. And two wires for triggering the relay network for the fog lamps. One of the trigger wires going to ground, and another that passes ground to the relay when the switch is in the "On" position.

A standard 5 pole relay should be able to be wired to the fog lamps like this.

+12V from the headlamp LOW BEAM output, and ground from the fog lamp switch will go the relay solenoid. This will allow the relay to only actuate when the low beams are on, and the switch is depressed. Any other condition will turn the foglights off. (i.e. headlamps off, or high beams on, or fog lamp switch off...)

You could then route a +12V fused link to the normally open pole of the switch portion of the relay, and the positive wire of the fog lamp assemblies to the common pole of the relay switch. This will allow +12V to pass through the relay to the positive power side of the foglamps. The ground side of the fog lamps can simply be tapped into any chassis ground point.

You could have the relay network and fuses all under the hood (Neatly tied somewhere not visible) and the only firewall penetration you would have to make is the ground actuation wire for the relay solenoid coming from the foglamp switch.

Not sure if it would work, but it may be worlds easier than trying to tie into the BCM... And the important thing here is that it maintains that stock appearance.

That's why I want the factory fogs... Stock clean appearance... Functionality at that point I will take any way I can get it. The less I have to tap into as far as factory wiring goes, the better...

No pressure taken Just finished going over the BCM programming and that is not going to work. The logic simply is not there.. What a bummer..
Basically, I am going from the low beam 12v thru a switch to the relay that is in the under hood fuse box. It really is a pain that GM did it this way but hey, that’s what they did..

The lower grille has the fog mounts for left and right. There are 4 screws under the lower fascia. Simply remove the four screws and push the old one out. I had to climb under and work the center out. Put the comp lower grille in and install the 4 screws.


The OEM switch is a momentary switch, so it does not hold to ground. It is designed to drop the switch circuit to 0 and raise it. The BCM detects the transition from 12 to 0 and switches a logic circuit. The current BCM at least before May 05 does not activate the pin on the BCM for the switch. I am still going to use the main fuse buss (just one more wire) and the oem relay and fuse position (already wired). So I have about 2 more hours of work and it will be finished and they look sharp.. FYI the terminals on the BCM are AMP/Tyco micro quadlok and power quadlok.... The terminals for the main fuse box connectors are standard GM 280 no tang..

Hmm... Sounds like a REAL fun time!

So were you able to make the factory momentary switch work somehow? I'd definitely be interested in finding out how you did this...

If this is all done via logic circuits in the BCM, that is pure bliss... More like a pure pain in the ass...

Could the factory momentary switch be used with standard mechanical latching relays? Also, what kind of illumination is in the factory switch?

I suspect it has standard panel illumination which lights with the dash lights, and possibly an LED signifying that the fog lights are on?

It may be a bit complex to get everything working without using the BCM knowing it's a momentary switch, but I am always up for a challenge!

I'm no engineering guru... Just an MECP certified First Class installer with an auto security specialist certification. I've had to design some pretty elaborite relay networks in the past for things like door locks and power window modules. I've also installed many sets of fogs, and this will be the first with a momentary switch... excellent
