Summary

Next question comes from Mike who's asked, can you splice essentially another circuit into an existing wire? Yeah absolutely that is my preferred technique of doing exactly that. Essentially we're replicating exactly what we looked at in the demonstration. This is something we will be doing from time to time particularly maybe you've got a factory wiring harness and you want to add in an additional sensor where you need to splice into the 5V supply and the ground, yes that's exactly the technique.

00:10 Essentially we're replicating exactly what we looked at in the demonstration.
00:14 This is something we will be doing from time to time particularly maybe you've got a factory wiring harness and you want to add in an additional sensor where you need to splice into the 5V supply and the ground, yes that's exactly the technique.
00:29 It does get a little tricky when you've got an existing harness because you're obviously trying to break into the middle of a wire somewhere and what that does is it makes it very difficult for you to apply sheathing so it's important, or SCL or something to insulate and protect the crimp that's finished.
00:47 What I try and do here wherever possible is actually extract the terminal from the back of the ECU header plug.
00:54 This can be tricky depending on your specific ECU.
00:57 Some are quite fussy on how you actually remove or depin a connector but once you've got that terminal out of the connector body it gives you full access to the wire and then you can apply some SCL over the top to protect it.
01:10 I do try wherever possible to make those splices at the back of the ECU header plug.
01:15 The reason for this is if we make them inside the engine bay or at other points in the harness, even with a crimp, it does still provide another area where we could potentially have a failure point so we want to minimise the movement of those splices so doing that at the back of the ECU header is the best place to do that.
