Differences between amateur and professional wiring? Options

[Tdskip]

OK guys - we have some very talented people here and I'm hoping to bring my wiring skills up a level.

What separates amateur wiring from a pro level? One item that comes to mind - no use of Harbor Freight connectors (which I am guilt of).

What else comes to mind?

I'll just add a little to the already excellent advice given. You can buy OEM (AMP) connectors at digikey. They are high quality and an exact match of what came originally in these cars. Here is a list of some of the part numbers I used rebuilding my harness:



You can use generic grommets but OEM are still available but a bit of a PITA to source. Most of the grommets are blanked sealing grommets so IMO, using open style grommets is not at a professional level as they won't seal out water or air like the originals. Here is a list of part numbers for most of the grommets. If you want the spreadsheet that includes source links, PM your email address.



As for soldering, follow the earlier advice and do not solder terminal connectors for the reasons @Superhawk996 described. From what I have read, soldered terminal connections are not allowed in aviation applications. That says something. However, DO solder wire splices if you have to make them. Use a lineman's splice , solder it, and protect it with heat sink. I match the heat sink color to the wire and add match tracers with colored sharpies just for that extra touch.

914Rubber sells OEM harness tape if you want to match the original. You can also get it on ebay. I think the brand is Telsa but can't remember for sure.

Hope this helps.
