I'm betting you'll revise your definition.

Look at this. It is from Alldata.


FRONT FOG LAMPS
With the ignition switch in the ON or START position, the front fog lamps will illuminate when the driver toggles the front fog lamp switch to the ON position. The front fog lamp switch is a momentary switch that requires the driver to briefly place the front fog lamp switch to the ON position and release it. The instrument panel module (IPM) controls the front fog lamp relay coil. When the driver toggles the front fog lamp switch to the ON position, the switch supplies ground to the front fog lamp switch signal circuit of the IPM. In response to this input, the IPM supplies ground to the front fog lamp relay control circuit. The underhood fuse block supplies battery positive voltage to the switch circuit of the front fog lamp relay. Ignition voltage is available to the front fog lamp relay coil when the key is in the RUN or CRANK positions. When the IPM grounds the front fog lamp relay control circuit the relay coil energizes, closing the switch contacts. Current then flows from the fog lamp fuse through the front fog lamp relay switch to both front fog lamps. Both front fog lamps are permanently grounded at G104. The front fog lamps will default to the OFF position upon a key cycle.

The IPM will turn the park lamps ON when the front fog lamps are ON and send a message via GMLAN serial data to the instrument panel cluster (IPC) to enable the front fog lamp indicator. The front fog lamps will deactivate when either the flash-to-pass or the high beam headlamps are turned ON. For vehicles exported to Japan or any European Country except Norway or Sweden, the front fog lamps will remain illuminated with the operation of the high beam headlamps or flash-to-pass.

So If I test the fog lamp relay when I turn them on, and write down all the values (ground, power). Then turn on the high beams and test the same relay I should be able to see what the difference is (loss of ground?) and then recreate that from whichever pin the high beam has the same of (ground to ground)?

I dunno, I've been reading too much Alldata too early in the morning.

why not just get a wiring diagram for the STS? sure helms has it.

[snum1fan]

I have all of the wiring diagram for the STS from Alldata. There is so many pages. I have been looking at it all morning, but what is a PITA is comparing different diagrams to figure out how they relate to each other. If there was one big diagram it would be easier. There is about 15 or so just on the headlights, not including the foglights.

I will post some of them. If we can figure out the best approach I will be the guinea pig, and try it out.

[snum1fan]

OK here it goes.

[staynumz]

The youngest guy has to figure it out first. I dont make the rules, I just live by them.

[STE_6000]

after u get that done, make a bomb out of gum and a paper clip hehe

[K STS]

what kind of mcgyver shit is this

[STE_6000]

diagram reminds me of shoot and ladder.

A dealer with a Tech2 can activate that in the BCM. I had this done and the fog lamps now stay on with high-beam.
