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
 

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.

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.

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.
