I am going through fixing my cars various electrical issues, and had a couple questions about some connectors I found that don't seem to plug in anywhere. Anyone know what they are?




Automotive tire Motor vehicle Gas Rim Auto part

brown 2 pin, almost looks like fuel injector connector, but I have a cable going to each of my injectors already, including cold start injector. Right next to throttle body
Bicycle tire Automotive tire Bicycle frame Bicycle handlebar Nail

grey 2 pin connector. This one is by the fuse box in the engine bay. Don't have a clue what it goes to.

These yellow cables do not seem stock. This one is in the passenger kick, and the car ran without it plugged in. I was thinking maybe a plug for some kind of audio system, but am unsure.

similar deal as above. Seems to be tied into the same harness as above connector. Again in passenger kick.

any and all help would be greatly appreciated!

Remember, many wiring harnesses are built to accommodate various different markets (US, JDM, and others). So, often you’ll see unused plugs because an option wasn’t purchased/ built into that particular vehicle. Also, left hand vs. right hand drive, regional options (folding mirrors, fog lights, audio options, etcetera). It’s often easier to build a wiring harness in one standard manner and leave a few extra plugs, connectors and wires rather than having to build 7 different types and deal with the logistics and problems during production. It’s cheaper and easier to roll with one version (or so). Best wishes with your gremlins!

Perfect! that makes a lot of sense, found the info iin the BGB looking further. Seems kinda strange to have connectors on the passengers side when there isn't an airbag over there.
the one by the TB is probably cold start injector? Maybe an idle up VSV, but I think that’s blue/teal.

one by fuse by is likely charcoal canister. Think the purge valve is integrated with it.

yellow stuff is all airbag as mentioned
