Ok just to Update this thread on terminals I have now secured a supply of the following terminals
TE/AMP 173681-2 - This is the one that goes into the blank space on the headlight switch. I actually ended up getting part number 173681-1 as this was available from Mouser in smaller lots. Not sure the difference, maybe wire size it takes? (EDIT: figured it out - 2 is "selective gold" and 1 is "pre-tinned", Bit of gold on the contact areas, we can do without that). These take 18-22 AWG so that's fine for this application. Link To Info on Mouser Site
7114-4026 along with the rubber wire seal plug - This goes into the vehicle side connector that houses the side marker lamp wires from the factory but you can add the fog light wires to it as long as you get the fog light harness from AU Holden Part number 92238667.
These wires would then go to some sort of relay set up to get power from the fuse box. Still have to work on that for myself. Plan on offering a kit if I can make it an easy install.
Continuing to add to this so I can keep all these numbers straight:
Relay to match the cooling fan ones under the hood is Hella 007794311 RELAY 12V 20/40A SPDT RES WTHR BKT
Connector for relay is Delphi 630 series 12065686 4P FM BLK CONN ASSY 630 SERIES 46 AMPS
Terminals for connector is Delphi 630 series 12020156 (maybe not that is a Pull to seat terminal #)
Terminals are listed below this is for the unsealed versions. Although the connector has a large wire seal on the botton of it I believe the terminals are considered to be unsealed ones becase there is not a seperate seal on each wire.
Wait, this image states the relay plug is Pull to seat terminals.
So that would mean these part number would apply:
Continuing to add: If you want to build your own for light harness down to the lamps here are a few numbers:
Delphi Connector to H10 lamps - 12059183 (comes with a seal)
Delphi Connector to H10 Lamps - 12059182 (connector Body Only)
Tan Seal - 12059184
12077411 - .5-1.00mm squared - 18-20 AWG
12077412 - 1.00-2.00 - 14-16 AWG
12077413 - 2.00 - 3.00
15324983 - red - 1.7-1.20 O.D. - 14-16 awg??
15324982 - green - 2.85-2.03 O.D. 12-10 AWG?
12059185 - secondary terminal lock (at back of connector)
Still cannot find the exact connectors that come on the AU Fog light harness mentioned elsewhere in this thread. Ones above will work, just not as nice as the Original versions.
