I need to rebuild the injector harness on an old vehicle using Y-splices on the wire to reduce cable usage/lengths (V12 engine).
My question now is how to to the Y-splice on the wires.
Soldering
Seems to be discouraged for automotive use, because stranded wire gets stiff and breaks under vibration. Also high temperatures on top of the engine makes solder brittle.Ultrasonic welding
Seems to be the professional choice - no access to such a machine tough.Crimping
I´ve seen a lot of bad homemade crimps - i´m not sure if it is doable with non-professional tools. However, this seems the way to go. Still need a way to join 2 wires- Butt Connectors
they don`t seem to be designed for putting in 2 wires on one end. Crimping Tubes (Aluminum) Found them at a rc hobby supply store - but they are not intended for (stranded)wire use at all
"Scotchlock" Type
They are intended for automotive use; however i don`t consider this a permanent or even sufficient electrical connection.
- Butt Connectors
Which method and tools should i use? Or is there a better way?
