Wiring an FIA Kill switch

[craig_mr2_mk1]

I've brought a FIA aproved kill switch to wire into my. Rev 3 turbo, I understand how to wire in the battery terminal but I believe there's another wire or more that have to be wiring to it otherwise the alternator will keep the engine running?
If someone could tell me which wire or wires need connecting too the switch that would be very helpful.
Thanks,
Craig.

The two main connection points for the power are pretty self explanatory, but you MUST make a note of which cable leads directly to the battery, and which one connects to the rest of the loom. This will be important later on.

The other four connections correspond to a normally open and a normally closed circuit. The circuit that is closed when the switch is in the "On" position is for the vehicle's ignition circuit. You will need to locate this in the loom, cut it and connect each end of the wire to one of the two connectors. Now when the switch is rotated to the "Off" position the ignition circuit is broken and the engine switches off - just the same as turning the ignition key.

The circuit that is open when the switch is set to "On" is used for the ballast resistor. One of the terminals should be connected to one of the points on the resistor and the other point on the resistor to a suitable ground. The remaining terminal needs to be linked to the thick power cable that supplies the rest of the car - NOT THE CABLE TO THE BATTERY. This protects the vehicle from any power surge when the power is cut. (If you get this the wrong way round rotating the switch to the "Off" position will connect the battery live to ground resulting in at least smoke, if not fire or explosion. You have been warned!)

Thanks for that Patrick, very informing reply. I don't suppose you know which colour wires they are do you to save me some time?

The ignition circuit you want to cut is black with an orange stripe and located near the ignition barrel.

Brilliant, I'll give that ago shortly then.
Thanks very much.

Could someone answer this for me as I haven't got a wiring diagram for the Rev 3 turbo.

I am looking for the ignition wire to chop for a kill switch. The white cable on the top left of the picture is connected on the ignition switch side to a black cable with a red stripe.

There's another black cable which has a yellow stripe connected by the yellow connector.

There's a little black wire with a brown stripe.

Which is the correct one to cut?



Thanks in advance,

Tom

Black with an orange stripe, shown on the left of your photo. You can prove it out by cutting it (with your snips) while the engine is running.

Thanks very much Patrick, much appreciated

Mega old thread I know, but shows I'm using the search function

When wiring a kill switch and mounting it on the dash, do I need to extend the main lead from the battery into the cabin?

As I ask the question it sounds obvious...

What gauge cable should I use?

Yes

Same as main battery cable.

You could on the other hand Google Cartek and do away with the old style switch same as me and Ash have done.

I've gone for the XS, very neat piece of kit and isolates ground from the battery instead of live

Very neat, but also very expensive.... Think I'll sort a few other things before buying one of those
