While diagnosing my no power to the ecm I found all these relays under the hood and I have no clue what they are for... any help would be appreciated.

And what is this guy for? There's a little circuit board inside it?!

More questions!!!! Does anyone have a picture of where the factory foot lamps are supposed to go in the interior? Mine are just laying on the ground..

The box with the circuit board is the diode trio. That tells the sol-vac to kick in when the rear defrost, A/C or headlight are on. The footwell lights normally mount to the rear of the package tray. I've only seen one mounting hole in an SX/4 on the drivers side. I drilled one for the passenger side.
Picture # 3, I have seen the fog light relay mounted in that location before, but can't remember if there might something else that also gets mounted in that vicinity.
Awesome! !! I was wondering where that diode pack was located! And the factory fog lights don't work ether, now I got a place to start diagnosis!
The factory fog lights (that I've owned, anyway) have all had issues with corroded or burned contacts where the bulbs seat. They use H2 bulbs.
Isn't the diode trio usually in the alternator?
hi, in picture #1 the small square one is the manifold heater relay, and the larger rectangular one is the horn relay. gz
Sweet!! I'm going to unplug them and test to verify.
I know what your thinking about in the alternator, there are 3 sets of 3 diodes in the alternator. The diode treo that were talking about on the fire wall is to boost idle when headlights are turned on, or the rear defroster, or the a/c compressor is engaged.
Ok, you need to tap the gas to get that to engadge. I turned the idle down then turned stuff on and that's why the idle went back up till I turned stuff off. Thanks

2 sets of 3 diodes in each alternator. (Delco ones) 3 windings in the alt with each stator set having a positive and negative diode to cut the other half of the Alternating current the alternator makes to turn it into Direct current, "rectifying" it.
