and how to crimp 1 wire to multiple wires like 0v5 1 wire from ecu to 4 to 5 wire of different sensors.

You use a splice -- sometimes called a butt splice (wires exit from each end), or I use the shorter ones and send all the wires out the same end (easier to hold & crimp), and I can cover with adhesive-lined shrink after crimping.

Here is an example of the parts I use:


Sorry to hijack but how to splice reliably is a question I've been meaning to ask.

Does anyone here uses the Deutsch DT Bussed Receptacles? I've been thinking about trying them. It may be a bit of a clunky way to splice but they look like an easy way to do it if you don't have the skills and want something reliable.


I've never used those, but sometimes I think that would be handy for power & ground. Lots of time, when I have to go back into a harness to add an additional sensor, CAN connection, etc.

Faisal - We do have a splicing section in the fundamentals course, but the video isnt up yet. We're working on it, and it'll be available in the next couple of days. Cheers.
