Default What's the best way of joining these Two Wires Together?

Hi Guys

Two unrelated problems could have caused a major Accident in my XJS, one of which was the snapping of the Alternator Belt but having fitted a new one and also replaced all the Belts with New ones She wouldn't Start

At first I suspected that the Crank Position Sensor may have either been damaged or knocked out of position with this Broken Belt that wrapped itself round the Crank Shaft Pulley like Spun Suger

But when I got the Car home on a Trailer, I tried to Start Her again today and She ran for 10 Minutes before cutting out but just before She did so, I saw a very tiny Flash from the Immobilizer Light on the Steering Column

So I tried Her again and exactly the same thing happened!

Only this time I was ready for it and held the Immobilizer Dongle as close to the Steering Column as I could and this time She kept running

Where by process of elimination I suspected a Fault with the Immobilizer, which has always been a PIA from day one, where you had to jiggle the Dongle about to get her to Start

The only difference being that on this occasion that Faulty Immobilizer could have caused a major accident and anyway I don't need it, as if anyone tries to Steal my Car, they are going to need a Crane!

Because with my home made anti theft device (which for obvious reasons I won't describe on here) they are never going to get her Started

Where as such I decided that the Immobilizer had to go!

Underneath the Dashboard there's a major mass of wires and what I know about Auto Electrics, you could write on the back of a very small Stamp and while I don't want to speak too soon

With the help of Greg's diagram and a bit of advice from 'The Wizard of OZ' I think I have figured it out

So one of the things that I need to do, is to join to Ignition Wires together, Similar to the ones you will see in the Photo

These Wires Carry Battery Amps (I think?) so they do need to be Securely joined together

So my Question to you Guys is what is the Best Way to do this?

I did think of 'Bullet Connectors' but the Wire is a bit too thick to go in there

Or maybe use that Junction Box in the Photo?

Or else Solder the Wires Tip to Tip or Solder them Side by Side with Shrink Wrap on

I have really no idea, just throwing some ideas around

Advice on the Best Way to go please



What would be the Best Way to Join Two Wires together similar to these?

Twitch wires end to end and finish off with solder and heat shrink or use a heat activated solder crimp sleeve.

These are the Narva Solder Butt Joiners.

Red = 3mm wire
Blue = 4 to5 mm wire
Yellow = 6mm+ wire.

Those wires you have will need the Yellow stripe joiners.

Solder, heatshrink is another way, but if access is tight, more solder will be on your arms than the joints.

I have used those solder joiners, and quite happy with them.

OOPS, forgot the image, seniors moment.

Hi Guys

Thank you all for those great suggestions!

As I know nothing about Auto Electrics apart from how to change a Bulb, as a Temporary Measure and because of the urgency of getting this fixed

I decided to go with the Plastic Junction Box in the Photo, as for one thing I didn't know if what I was doing would work but since it does this Temporary Fix might well be permanent, as it does the job extremely well

And I was a little bit (make that a lot!) Paranoid about using a Hot Soldering Iron inside the Car, in case I accidentally burned a hole in the seat or something

I like to solder. I made two "elegant" wire vices to aid in making a clean joint.

1. Coat hanger wire bent into a "Y" shape., Aligator clips at the two ends. Clamp the ends there and solder the joined ends in between.

2. Two wooden clothes pins screwed to a block of wood. Each pin is the vise to hold the wires in place to solder

But, most of the time, I merely twisted and soldered then shrunk on the tubing.

I read of a very elegant way to do it!! Managed a time or two. Need two strands of corroded copper that will not accept solder. press the two bare end together, not twisted, merely meshed. Secure the meshed with the strands, one at each end of the bare wire mesh. Solder. Remove the corroded strands that did not accept the solder.
Slip on the tubing., Apply heat and shrink to fit

Result a smooth integrated splice.

Caveat. Use "good" solder. Silver or Rosin core. No acid core, for sure.

When I did my Lump, I did a lot of solder. In the cabin and in the engine bay. Carefully. No burns. I used book matches for the heat source!!

Now, I've a pair of heat guns that are far better. HFsourced, not expensive!!

Clean solder gun tip. Well tinned ands things "flow" nicely. I've several. From pencil size to really "big iron". And a pair of 'racks" in which to rest a hot iron...

I always solder and heat shrink my wires however the above I have never seen. Just ordered some. Thank you.

I use these, they came from the telecommunications industry and were used for repairing underground transmission cable wiring. No soldering iron needed just a heat gun.
