David,
Thanks for your reply, the information you gave is the same as what I already have but my question is relating to a group of wires not connected to anything at the moment and all bound up together as a group with black insulation tape holding them all together.
These wires were connected or maybe they were intended to be connected to some equipment at one point; that is really what I am trying to find out. There is no trace of these wires in the vicinity of the fuse board or surroundings, they just disappear into the very chunky wiring harness behind the dashboard.
My ammeter is wired correctly, as is the ignition switch etc. and everything worked ok except the clock which had never worked. I sent the clock away for repair only to find it was a positive earth instrument which surprised me a little, but it is now repaired and working.
Roger’s post referring to a post he made in November 2019, whereby he attached a wiring diagram for the 410, clearly shows the white wire coming off the live side of the fuse and going directly to the fuel pumps. This will be my point of access to the wiring for the switching. (Thanks Roger for highlighting your old post.)
With relation to the SU Dual Action Fuel Pump: My existing pump died through old age and probably the addition of ethanol in modern petrol. I decided to buy a Bosch electronic inline fuel pump as a temporary measure, it works very well but I don’t like the whirring noise which is constant, I prefer the gentle tick of the SU Pump. I sent my old pump to a specialist for repair rather than buy new and even though I haven’t fitted it yet, I am very pleased with the appearance and I know it’s been pressure tested for compatibility with my Edelbrock carburettor, which incidentally I had tuned and calibrated by the same person before fitting. A few photos attached of before and after. (Only able to attach after photo)
