Thanks stevie, as always. I have seen a few diagrams with 86 & 30 looped together and triggered from ground. This is what was getting me confused! Been doing other bits at the moment like fitting fuel lines and radiator lines to the rear (what a pain!) but hopefully be back on some serious wiring at...

I'm ashamed to say I am still struggling with all this and not making any progress. I appreciate your comments Stevie I really do, but I just cannot get my head around it, there's different ways to do this and a lot of "you can do it like this, or like this, or like this but it depends on XX" so you...

It simply means that the ecu provides the ground to trigger it. ie pin 85 on your drawing. Pin 86 would just take a 12v, whether you make that permanent or via the ignition switch is up to you. I tend to like adding a manual switch for this relay too...again to the pin 85 via ground in case you wan...

Yeah, didn't really understand most of that Stevie. The diagram was cobbled together with a little help from Rich. I'm still struggling to find any useful/consistent information. I would have thought there would be a lot out there for beginners but apparently not! For the most part, there isnt much...

One tip as regards drawing things out is that for a schematic, you don't need to situate the components were they are. For example, you don't need to show all the fuses in one block - just because they are. They can be shown anywhere in that circuit. You also need more wire colours. Each fused circ...

I know there are mistakes in this but it's as far as I have gotten, but I don't know where to go from this. Some people tell me a 100amp breaker is fine, others say I need a 300amp for the starter and 100amp for everything else, but no one actually says where they need to go .... Rich has already sa...

If you have a plumbed in fire system. It has to work even if the kill switch is pulled Ian It does, it's entirely mechanical and not related to the electrical system. There are two pull chords, one outside and one next to the driver (same for the kill switch). Also have a separate hand held extingu...

Right, well Richard has kindly sent me an email with a bit of an explanation which has helped a lot, sorted out a few things I was confused over. Which has made things a lot better. Relatively busy this week but will try and get something done later on and report back!

For reference the race series is the BARC CNC Sports & Saloons Championship, my car fits under Class A rules. The rules are very open, but for electrics it only states that the brake lights need to work. And then standard safety features e.g. the rain/warning light and fia kill switch: "One electric...

Do you have the regulations for the class of racing you want to go into? There may well be something in there that is specifically required, and, guidelines to put kill switches here, here, and there. MSA Blue book regs. Need to run an FIA kill switch with external/internal pull cords, and a rear r...

OK well this is why I am asking for advice, I have read around a lot and done the best I can but I don't know if it is right or what needs changing. Yeah Dave I was surprised that I couldn't find a diagram or diagrams to try and help me. The point of the fia kill switch is that it kills everything, ...

The kill switch kills everything, it's a proper FIA one not just a battery isolator. Have internal and external pull cords. Still havent a clue what i am doing, any suggestions if that diagram is ok? Or what's wrong with it? Thanks

Righto, quiet morning at work has meant I have bashed my first attempt at a wiring diagram. This is for the main engine wiring loom, covering battery/alternator/starter, and the FIA kill switch. I'm not running a key/barrel lock type ignition switch which is why I have drawn it the way I have, using...
