    yeah the 2nd pic is the ECC TEST CONNECTOR. it's under the coil cover, next tot he shock tower.
    I can't tell enough about the first pic to tell where / what it is. kinda looks like the connector that attaches to the T5.

    the EEC test connector is for plugging in to something like this.

    the other connector is under the tunnel. reverse lights, and neutral switch, 75% sure on that one.

    Yes Eric that is the connector for the t5. I lost the other part but can get it online. It has 2 wires on it which i believe connect to the red wires. I have no idea what the white wire connects to.

    as I recall (off the top of my head) -- the red wires just loop.

    I think the white wire goes to the clutch switch, I'm looking through wiring diagrams to see if I can find it.

    Here you guys go, I scanned in the 86 EVTM below along with a pic that I found with my own 86 connector. The color code on the 84 may be slightly different, but the circuit should be identical.

    The red wire is definitely looped and there should also be 2 more wires in the connector, which go out and back from the tranny switch. The EVTM also notes that Connector C107 should have 4 terminals. It also states that the connector should be brown and it is certainly gray. Hope this helps.

    Thanks. i will have to see if I can find one somewhere at local junk yard. There isn't any where I live I will have to check junk yards in Detroit if I can get across border with all the new virus closures.

    Could you change / update those connections to a weather pack or similar style of modern connector?

    That may be the 'better' option, since you are having to get a replacement connector/pigtail. I changed a couple of connectors in my engine compartment a few years ago due to temperature degradation behind the intercooler. You can see how that went over in my "17 years and counting" project thread. For this location you would need a 4-pin connector.

    Definitely better. If you try to butt-splice that connector back in, you add two connections per wire in that plug, which provide two more opportunities per wire for failure down the road due to fatigue/heat-cycling/corrosion. Adding the appropriate terminal to the end of the cut wires and inserting them into the appropriate connector housing would be much more reliable.

    Unless you're going for a 100-point concours car, this would be the more reliable route, IMHO.

    I am firmly against butt-splices, and won't buy a car that I see them in the wiring...
    solder and heat-shrink is the only way to go for that kind of stuff.

    When done correctly, it's very good connection, and you physically cannot pull it apart.
    Watch out for the cheap knock-offs, those are junk. If the the price is ridiculously low vs all the others, there's a reason.

    I still shrink wrap over the top for aesthetics.
