How To Splice | Practical Wiring Demonstration [GOLD WEBINAR]

Splicing a single wire out to multiple wires is something that must be done multiple times for every harness build, and there are always questions about the best way to go about it. In this webinar we'll look at how we size the splice to use, the required tooling, where the splice should be located in the harness, and perform a practical demonstration of the process.

Due to the current global situation we though over the next few weeks we'd help keep you guys out there entertained and release some of these otherwise webinars to you for free to help pass the time.

Want to watch the members-only webinar on Engine Build Considerations or Engine Failure Analysis along with over 230 other lessons on engine building, tuning, and wiring topics? Grab the course above and we'll include 3 months of free access in the purchase price.

Pleasure to get real-world advice from an expert. Thank you. Well done.

I like to leave a little more bare wire prior to the splice, about the width of the splice itself. This lessens the angle of the wires as they enter the crimp as the insulation being up close as in your example bends the extreme strands quite sharply where they enter the splice due to the diameter of the insulation. And the shrink wrap will easily cover this slight extra amount of bare copper outside the crimp.

Watching these videos is extremely validating. Many of your best practice techniques are the way I've been doing things and being told it's wrong since I was a teenager in the 90's. Others are adjustments I've made after finding failures and having a think about why they occurred.

I’m very happy to here that you prefer crimping instead of soldering. I found so many soldering videos and so little good ones about crimping. - Thanks. - Can you please produce a video „crimping vs. soldering“? This would be very interesting!

while the FAA recommends against soldering anything, they used to have an emergency procedure for solder repairs of wires. basically it involved wrapping each wire around the other 4x, soldering them, adding some sealant to the heatshrink tube, and then shrinking it. reference FAA AC65-15A for the exact procedure. disclaimer, this method is not in the AC 43.13

My personal hack for replicate the Raychem MiniSeal splices (for lab use and personal applications only) is to get the generic "Non-Insulated Buttsplices" (has to be the extruded type and not the stamped type with a slit along it) and a generic solder sleeve where you gently crush the solder with a pair of pliars and remove it from inside the heatshrink. Heatshrink with glue will also work fine, preferably see-through.

Crimping the "generic buttsplice" and then add a "solder sleeve" with the solder ring removed, only having the two glue rings will essentially replicate the MiniSeal connection for 1/100 the price.

Fantastic content once again guys! Giving some new people the chance to look at what's in store in the wiring courses, as well as the gold member only webinars!👍

In the industry I'm in (railroad maintenance) my preferred terminals of choice are insulated double crimp terminals for small gauge wires (which are 18g up to 10g). Everything else that's 8g or larger (up to 4/0 typically) gets a brazed barrel terminal. I will occasionally used a non insulated brazed barrel terminal with heat shrink on small wires, but the double crimp insulated style is more reliable, easier, and certainly faster.

I've used that open barrel crimp tool on pins, but I've actually found that style of pin to be less robust than the [DMC AFM8] style crimper and pins.

Great vid loved it, why and how answered.

[jc.considine]

Great video. Thank you. Especially appreciated the comments about ECU sensor earths.

[joshschaefer]

This is a terrific video. Very informative and crazy helpful. Very well done.

When the Russians made the wiring harness for my Lada Riva, they used national grid grade wire. Each wire is an inch thick.

[sparkiekosten]

Gee It must be good to have steady hands!

[boudewijnv.kempen]

This is awesome. Would like to use it in my project car but i can not find anything here in europe. : (
Great vids btw!!
Greetings from🇳🇱

Circular mils? The US will really do anything to not use metric won't they. As if AWG wasn't stupid enough, now it's combined by pi=4?

[christianbrennan]

It's like dropping a bolt in the engine bay 😀😆

[shishajuwan]

What is the name of the connector that joins 4 wires together. I can't find it online

[nicholasseeger]

Hi Zak
Quick question is the Crimping tool CT 3137 that you quote the same as the CT3187 I can find online? Great videos by the way - learning a lot

Coming from being a MECP certified, installer club and pro grade motorsports wire connections are way more regulated and detailed compared to mobile electronic wire installations. How are high silver content stranded wire compared to copper stranded wire since silver is supposed to be a better electrical conductor than copper? Is the silver to corrosive? I also think about causing more resistance in a splice especially when the wire is going to the ecu where it involves a sensor signal where it’s more critical to the ecu like Motec.
