Joining multiple wires?
tegwin - 24/11/08 at 12:31 PM

Due to bad planning on my parts I have ended up with about 6 wires comming back to the same point under my dashboard..... I need to connect them together so the joint is electrically sound...

How can I do this? Soldering more than one cable together is a mess....Cant think of any way of getting them all tidied away....

I'd solder and heat shrink them. It'll be the strongest way of connecting them up.

Don't worry if it looks a mess, just make sure you get plenty of solder in the joint.

If it's earth then bolt through tags.
If it's live then a small fusebox.? Allow disconnection for faultfinding.

terminal block with a wire on the back going from port to port to connect them all up?

Closed end connector, Vehicle Wiring Products should stock them. Rescued attachment closed.jpg

that is a very common problem yet there seems to be no neat way of solving it.

What I did on once (thin wiresfor LED instrument lamps) was to twist the wires together then put into a terminal block - not nice.

Another case, instrument lamps again, was to make use of the tags o nthe instruments and solder wires to make Y joins; again not nice.

Take a look at VWP - they do a multi-way terminal connectors for spade terminals.

e.g. ... that you can make by cutting up some flattened copper pipe or there is a 4 or 6 way multi bolck in plastic housing, about £ 7, that I canot find at the mo'

Realistically you want to try and avoid that when you're planning the loom

Is it an earth? If so I'd just put eye connectors on the wires and have a little "earthing bolt". Not sure I'd want to do that if it was a live....

How about getting an off-cut of something like veroboard (with one strip of copper). Solder them all to that and wrap in amalgamating tape to insulate.....

5 piggyback connectors and a normal spade connected together and some tape?

Car builder solutions do 3 & 5 way multi block connectors for common connections with spring clamps operated by a lever. Used some when modifying the origianl sierra loom im using very tidy and easy to connect or disconnect if you need to untangle things.

if its earth - just solder them - the 1st strip it quite long - then the next twist it round that and so on - keeping it narrow and tidy.. use heat shrink to cover the lot - add a crimp to the end - ie a ring to the chassis
