Oops, I've broken it

[Drew20]

Does anyone know how the wire from the oil pressure switch is routed to the warning light in the dash, aka the idiot light?
I've snapped the wire (arghh) whilst fitting a VDO dual sender, for my gauges install.
About 6" of wire came away, from somewhere down the back of the head. Getting a soldering iron down there would need the head out I think, so looking to do a semi permanent fix somewhere else in the engine loom.... and then repair the loom properly at a later date

I've scoured the media section for an image of a car without the head fitted, no joy.

Thanks

that wire attaches to a female spade which then goes onto the sending unit at the back of the head

Thanks Steve, found it. Access was not as bad as I thought, down by the starter solenoid. Have replaced the connector and the wire. The copper by the connector was not in good shape!
Pressure sender fitted. The kind of job which makes you wish you had Donald trump's hands!
