Wiring harness plugs.

I'm making a wiring harness for for a gauge pod and I got these off the big A****on.  Dropped them off late last night, found the envelope on the porch this morning. Just thought I would show it, I'm happy with the quality.  It's a 12 pin connector.  The other is a two wire bullet extension.  The reason I got this, is a, it was actually cheaper, b, but look at it.  Flipping it keeps red to red, and black to black.  I wanted a more hearty connection for the voltmeter.  I used to just go to pick n pull and chop off connectors of whatever size I wanted, but its a different world we live in now.  Just ain't worth it.  Where y'all source harness connections?  Cause now I'm thinking about redoing something, I probably should have done the first time around.  Oh, and Merry Christmas!

Re: Wiring harness plugs.

Like anything you can certainly go down a rabbit hole with wiring. When I installed the Megasquirt in my Lightning I built the entire engine harness myself. I started with Weatherpack, but those can get really big for multi-pin connectors. Then I went Metripack, which are good, but I wanted better. Finally I spent the money on a good Deutsch crimper and connectors and have only used those ever since. If it is something mission critical like a crank sensor I go here (https://racespeconline.com/) and get real Deutsch stuff along with their solid pins. For "less important" items I snag the Amazon equivalents and don't look back. Also been using this for sheathing as it is really nice! https://racespeconline.com/collections/loom-supplies-1/products/high-temp-fiberglass-sleeving. Then of course I like to use a quality adhesive lined heat shrink.

Oh man you should see some of the high-end motorsport wiring harnesses with concentric twists and all kinds of expensive shrink boots and Tefzel wire. That kind of stuff will bake your noodle

Re: Wiring harness plugs.

I also used Weatherpack terminals for years, but agree with Raymond that they get bulky once you go much beyond 3 pin.  Deutsch are definitely the way to go now.

Re: Wiring harness plugs.

Greg B - A suggestion; as it appears this connector came with pigtail extension wiring that maybe all the same length, consider cutting some a little shorter to make the splices to these wires at different distances so that the wire bundle created is not as bulky as if the splices were all in the same place.

If you are going to splice the wires, then I totally agree.  However, if you can simply depin the connector body and crimp pins onto the wires you have that's how I wold prefer to do it.  I'll only make a splice if there's no alternative.  Even if you solder it and use shrink tube it's still a potential failure point.  Solder also changes the resistance of the wire, which can make a difference on things like injectors.

Re: Wiring harness plugs.

I'm going to re redo the dash wires so they are on the 12 pin connector.  It's already been cut and spliced and such because of a previous owner.  In the end there will be three plugs.  One for dash, one for gauge pod, volt light, oil wires and tach, and the two pin for the volt meter.   I wasn't ready to show off what I've been working on, but what the heck!  This is the last version I am doing!  Unfortunately it has to go in as one piece.

Looks good!

Re: Wiring harness plugs.

I agree w/TKO re: de-pinning the connector and suggest "electrical connector pin removers" as found on Amazon.  I purchased a 'kit' with multiple removers and have found it quite useful.
