Hi Richard,
Thanks for your ongoing support, I just wanted to double check as on British cars a blue wire with a yellow trace is normally used for long range driving lights (switch to lamp), for the equivalent circuit assigned to fog lights the British standard would be a red wire with a yellow trace. That aside I'm sure there's some variation in the standard as it's the great British motor industry after all, and Lucas the prince of Darkness was known to take a fairly lax approach to the rules
I now have to admit I've been trying to find the circuit by lying on my back looking up into Monty's front wheel arches, clearly this isn't the best approach, so I'll now proceed to jacking and supporting the car before removing the o/s front wheel. This should give me a fighting chance of locating those elusive pair of blue/yellow wires. In my defence I've been hindered by Waxoil, all surfaces under Monty are covered in a sticky brown/black coating, this is good for corrosion protection but not ideal when trying to find wires of a specific colour
One last question regarding grounding, am I correct to assume the blue/yellow wires I'm searching for are the live feed and the fog lights Morgan used (if fitted from new) would have grounded through the lamp itself to the car body? I ask because rather than grounding through the lamp my Marchal fogs each come with a separate red live wire and a black earth wire, so if I'm assuming correctly and the Morgan circuit is a switched live rather than switched to ground I will need to ground the black Marchal wire to Monty's chassis/body?
I'll certainly steer well clear from grounding to the engine block for fear of generating any voltage offsets/earth loops that could play havoc with injector durations and or the crank position signal, been there done that with my TVR and it wasn’t fun!
Thanks again everyone
Dave.
