Quick left signal wiring

[DissFigured]

Which image is accurate the top one or the bottom one?

I currently have wired like the top but I got to thinking and I wasn't sure and the diagram does not really answer this question.

Thanks

OK, I swear I have a college degree in software engineering and these are simple dumb questions but I have to ask anyway.


This seems to be the universal signal for ground and so I am led to believe the top picture is correct

So the question is... Anywhere I have a ground wire, can I solder it to any metal on the car frame? I would think I could sand a small section of the frame to ensure bare metal is available and solder ground wires to it. Is solder strong enough?

Yep that is the signal for ground, and the top picture is correct.

As far as grounding to your chassis, I wouldn't solder to it, not only is the solder not strong enough but I doubt you'll get solder to stick to your chassis. I would just use a crimp on connector with a self tapping screw into the frame.

Yes, the top picture.

You would have a hard time getting the chassis hot enough for solder to work properly. As stated by great 68, use a crimp terminal.

1. Choose correct size terminal, Strip wire

2. Crimp

3. Solder (optional - If you solder, clean flux residue off - isopropyl alcohol works good)

4. Heatshrink over wire/terminal crimp area (optional - It helps protect the wire and looks better)

5. Clean metal where connection will be made. Drill hole or use self tapping metal screw and fasten securely. It might be a good idea to touch up the exposed bare metal area with paint to prevent rust.
