folks,

It had never crossed my mind before, but does anyone know whether S1 Vixens are negative or positive earth? I don't have the original coil so I can't see the markings. The only one I have good photos of in this area is converted to alternator and is neg earth, but could have been changed over.

OK, I am pretty sure the answer is negative earth, thanks Neil
Cortina 1600Es were negative earth, which is where my gauges come from and the only tacho I have says 4 cylinder negative earth on the front in (very) tiny writing. So as long as I have the correct gauges, then I think i am right....

incidentally, in order to discover this, I opened my box of assorted wiring. The loom has been cut into at least 4 pieces, and none of it is labelled.

think I need to sit down with a cup of tea now

Fortunately wiring is some time away, but I am hoping to get the engine in the chassis in the next month or so, so I need a basic loom so I can make up a control panel and start her up (rubs hands in anticipation!)

Yes, the plan is to create a minimal loom to get it going, then to add in some of the ancillaries to test them (tacho temp etc). I think the last owner may have been thinking of splitting the loom with multiway connectors, but I don't think it's a good idea to reuse an already hacked about loom. I may use it as a guide the build my own, or maybe buy a ready made one. I think Vixen looms are available.

I was hoping to update it by adding in some additional fuses and relays, for safety.

Out of interest, does anyone know how much it would cost to get it done professionally?
