Default Good source for wiring?

Any good places to order 5’-25’ of different color wire? I need to extend wires for the drive by wire pedal plug and OBD port and trying to stay with the stock colors.

If you have a local electrical supply house, they might be able to help you by either selling to you directly or pointing you to a retailer who does.

For one or two connectors like that, I personally prefer to grab the connector with as much wire as I can separate from a "pull it yourself" parts yard. There are two advantages to this:
  1. You get the correct wire sizes and colors
  2. You have only a single splice in each wire instead of two splices (at each end of the piece you add)
Grab as much wire as you can trace back from the connector, and try to locate your splices in a fully supported, straight(ish) section of the bundle. Try to stagger your splices so that at all points along the bundle, there is only a single splice/heat shrink tube in the bundle at that point.

Thanks, I try to grab stuff from the u-pull it yard most of the time but if I can just order a few deals of wire I’d rather do that than hunt for the longest connector. I’m getting lazy with some ****, lol.

For automotive use, you want stranded automotive "primary wire." Napa usually has the best assortment locally for me. You can also get it at O'Reilly and other auto parts places, usually the Dorman brand. Online you can get it from RockAuto as well. I also ordered some online from a decent source a couple years back for a special harness I was doing for someone. I'll check my online banking and PayPal history and see if I can find that source for you.

Electrical supply places tend to have house wiring, not automotive wiring.


Update, the place I got some automotive wiring from for that project was Wiring Products Ltd. https://wiringproducts.com/collections/automotive-wire I'm fairly picky about wiring in general, and their wire was at least as good as OE wiring.

I got most of my automotive GXL wiring from here: https://www.wirebarn.com/GXL-HIGH-TE...-WIRE_c_4.html

Hmmmmmmm, but all I can say is if you need GXL rated wiring for your OBD-II port and your accelerator pedal harness, I think you have other serious (thermal) issues. I certainly don't want to drive or ride in your car if you need wire of that spec in those areas.

The best place that I found is your local pick and pull. GM minivans are an awesome source and have huge bundles of wires going from the front of the vehicle to the rear. Every color I needed to rework my harnesses was there and it only cost five dollars. Buying new wire from vendors is EXPENSIVE no matter where you get it. Good luck

The junkyard is cheapest and most factory, but I bought a big array of different gauges and colors on Amazon (stranded copper). It's really nice to just grab a roll of the right gauge and color.

Wiring ages,, Pulling 10+ year old wire out of a junkyard may not be better just cause its "OEM" especially in the engine bay.
Of course I'm working on a 1994, so there is that. Most of the stuff my vintage is hard as a rock.

Painless kits turn out to be not too bad price wise if you price out all the wire,
connectors and tools to properly crimp all the finicky connectors on a car..

I have about 400 bucks in wire/connectors/tools on my swap.
I thought just using my stock harness and matching what I needed to my terminator max would be cheaper and less work. Not.
If I had to do it over,, I'd buy a harness kit from Painless.

DIYAutotune.com also sells lengths of TXL wire bundles.
Here's one for example: https://www.diyautotune.com/product/...g-bundle-long/

I'd actually second the recommendation, I use TXL/GXL/SGL everywhere (so does Painless, Holley, and a few others). It's not necessarily that it's needed for its thermal resistance, the wire doesn't melt, it's self-extinguishing, and it is highly resistant to abrasion (if you scuff it, you can actually mend it with a little bit of heat), and is resistant to break down from automotive chemicals. Plus, it's just easier to buy one type of wire instead of switching between PVC and XLPE types. However, you're absolutely correct, in an OBDII port under a dash, XLPE is very much overkill.

Del City is lower price than Wire Barn but you have to buy 100 foot at a shot. I confirmed wire is made in USA. Only offered in solid colors but a good selection of colors.
https://www.delcity.net/

Allied Wire and Cable has wire with tracer colors. If you're patient then you might be able to get it cheap from their project scraps. Their idea of scraps can be 300 feet so that's a lot of wire to guys like us.

I use Waytek Wire for all of my wiring, connectors and terminals. You have to buy in bulk, but it's way cheaper in the long run.
