Ok well I know opinions on them are divided, but those who do want to fit them I thought I would create a guide, as I found it impossible to find much help and I could see a lot of people asking very similar questions. Anyways, here it is!
I have an 02 plate VTR, so the coilpack wires may be different for your car, so check that before you start cutting them all up!
Now this is very simple to do, I am not mechanically minded and not very good at all with electrics, but I managed to get this all done in just half an hour.
First things first...here is the limiter in its box.
And below are all the tools you need:
- wire strimmers
- wire cutters
- insulation tape
- block connectors (scotch connectors are supplied but they're crap)
- torx screwdriver
- socket
In the box you will get a diagram on the instructions that looks like this
This shows pretty simply the wiring that you will need to do. Simply you can split the installation into 3 easy steps:
Earth.
Power.
Coilpack connections.
Now first thing I did was disconnect the battery. I doubt it is necessary but whenever you play with electrics I think it's a good idea!
Now we shall start on the first part of the set up - the earth.
You want to cut back some plastic off the BLACK negative cable coming out of the omex box.
Then you put on a ring on the end of the wire. Due to earth point I choose I needed a larger ring, but there are some supplied with the limiter.
Then find an earth point, it is always better to use one that's already there rather than just screw the cable into any bit of metal.
I choose the earth point behind the carpet in the passengers footwell.
Now we have an earth, it's time to set up the power supply. In my opinion the best choice is to use the supply to the headunit. If you follow this route then you want to connect it to YELLOW wire, as this is the ignition not constant supply, basically so the box won't drain the battery and constantly be drawing a supply.
So you want to remove the headunit. I also removed the centre console so that I can tidy up all the wires nicely behind the carpet when I've finished.
So having found the YELLOW supply, I cut this in half, strimmed the ends, did the same to the RED cable coming out of the rev limiter. I used a block connector as I hate the connectors that were supplied.
Once all connected up I wrapped it all up in insulation tape to protect it.
And that's the earth and power set up.
Now we need to connect the rev limiter to the coilpack. You need to feed the wires through the bulkhead somewhere so that the two BLUE cables can access the engine bay. Each Saxo coilpack seems to be different, but on mine the two cables that I needed were PALE BLUE and WHITE. In order to find the wires you want to find the plug that connects into your coilpack, pull back any covering on the cable feeding into the plug from the loom and pull out your two NEGATIVE cables.
I already had a hole drilled through for the power supply for my amp, so I fed the cables through there.
Once in the engine bay you need to make sure the blue cables are out of the way, won't rub on anything, aren't near any moving parts and can be tied out the way.
I sent them along the inside of the engine bay, and cable tied them out of the way.
Once you have found your negative/signal wires into the coilpack it's time to cut them, trim off the ends of them and the blue wires, and connect them all up.
Once all connected up it's time to insulate it all up again and you're all connected!
Now you're all connected.
Then you're gonna want to tidy it all up and mount the box unit somewhere.
I wrapped up all the cables, and using the sticky pads on the back of the box I stuck it onto the side of the centre console down out the way.
And there you go! Hope it helps those that wanted it.
