joining 2 wires to 1
jabbahutt - 30/1/08 at 02:55 PM

Afternoon all

I'm wiring in my rear lights and would like to clarify something. I've read the threads on soldering/crimping etc. but this is slightly different.

I have 2 rear tail lights on each rear wing. Each has a +'ve and a -'ve. The loom is obviously only designed for 1 light unit so I'm going to end up with two +'ve connecting to 1 on the loom.

What's the best crimping method as shoving two wires into a crimp designed for 1 seems a bit gash to be honest and my soldering isn't that good and the wires are a bit awkward to get at so I think crimping is the way to go.

Any input on connector typres etc much appreciated as I'd rather spend a bit more money and do it properly than spend the rest of my days chasing electrical faults that could of been avoided.

Cheers all
Nigel

2 wires into one crimp is used in all sorts of places on a factory equipment loom.

just make sure you use the right size crimp, and you shouldn't have any problem.

yep - I second that.

I twist the two pairs for wires together then crimp - if your crimping technique is good, then there is no problem.

two laternatives is to use
a) bullet connector (4 way but you would use 3 ways).
b) 2 way spade

anotehr method is to connect one wire to the lamp and tap into it - carefully strip of a ring of insulation, wind the other wire around it and solder. Cover with heat shrink and job done.

2 into 1 goes fine for crimping IMHO it's the best way to do it.

How's the car coming on Nigel - any progress pics?

Hi Nick

Photos soon as long as I can get the thing out of the garage! the weather seems to know when I'm either going to spray paint or push the car outside

Scotchlok splice? These are insulation displacement things you close with a pair of pliers. They are fine for a take off for most things and can be removed with minimal damage to original cable.

*hang your head in shame sir!*

Them things ought to be banned.. I can't think of a place where somebody can excuse using one of those.. they are a complete and nasty bodge!.

Hang on a min, They're fine unless its your own car, and then you should do it properly.

Sotchlocks are ugly but effective --- I have never had a problem with one in service.

solder every joint and insulate with heat shrink tubing, it is the only way to reliably make any loon junction, especially it wet blighty

There was a time in our old regime that you'd've got the sack for using a scotchlock. I've seen many of them fail sometimes with added consequences. I'm a big advocate of the heat shrink splice.
