could you run two wires from the source?
.
I have always wondered what the answer to this question was, but now I actually need to do it, so I'll ask.
I'm running waste spark, and as such I have 4 wires out of the ECU going to 8 coils.
Which, ofcourse, means I need to split each one of the 4 wires in two, and then run them to the 8 coils.
EG
/----------------Wire1-------------------- Coil
ECU ----Wire------[Split]
\-----------------Wire2-------------------- Coil
What's the best method to do this?

IMO, trim back about 10mm of wire from the end of the wire you want to join, and where you want to join it to, give them a twist, solder, heat shrink, profit
Hello.
Yeah, I was thinking the solder, heat shrink jobbie, still might do it.
Hey man,
I'm not sure if this is the best way, but its the way I do it.
Get a single pin connector (like this)
Crimp a single cable to one side and then crimp two wires to the other terminal.
You can prolly forego the connector bit, but I find it makes it easier.
And you can obviously use the similar prinicple for any number of connectors. (i.e. get a 4 pin connector and have two coils connected to each pin).

Although any sort of crimp terminal will do the job (very nice crimp btw) there is always a risk it will come loose and give issues. If you solder it properly and seal it well with either heat shrink tube, tape, liquid or even just insulation tape you will have a more reliable connection. Bit more effort but you know it's done right.
Also it's a good idea to tape it into a loom and fix it to the body to help prevent movement. If it moves it may wear through on something or the wire might fatigue and break.

Hey, I like that crimping, that's pretty neat! I don't think I'd be able to get it that well crimped though, that's my problem.. :-)
Buy the correct type and decent quality crimping tool and a monkey could do neat crimps like that all day longOriginally Posted by stradlater

Only problem with soldering is you have the risk of the wire breaking at the solder joint because of vibration etc. If its actually supported properly you shouldnt have a problem, but crimping would always be better.Originally Posted by willwal98

But not in the case of the crimp terminal above - that with solder wouldn't suffer from that problem. It holds the insulator as well as crimping the core.

Whenever I crimp terminals I always try and chuck a bit of solder in there as wellOriginally Posted by Hydra
Call it insurance, whichever way you look at it (crimp with solder, or solder with crimp)

You wouldnt need solder to begin with. if the crimp is done correctly theres no need for solder.Originally Posted by Hydra

Hrm....
So maybe crimping is better?
What's the best crimping tool then? I've got a few of those normal ones, but clearly there is something better?
Use the correct type of crimper for the type of terminals being used. they're all different.
Sadly a Dick Smith jobbie with the 3 sizes marked red,blue and yellow can't be used for every terminal out there...

Get one from an electronics type shop eg Jaycar that can "roll" (sorry I don't know the actual term) the crimp just like the one in the pic above (when using that type of terminal of course).
Those crimpers from Supercheap etc are just crap and only perform a crude job of a crimp on those shitty pre insulated terminals.
When I rewired my car this year it was a combo of crimping and soldering or one or the other depending on the termnial type and its location/use.
A good crimp job or a good solder job or combination of both is fine i.e. you are not likely to experience any issues, a dodgy crimp and a shit solder job will lead to failure or intermittent issues.
Just do it well either way and you'll be fine
