water/oil temp gauge

[old gimmer]

I'm fitting a oil temp sender to use switched with the water temp gauge, there is a black/yellow wire by the oil temp sender any tips on where to find it under the dash on a 2004 SV please.

Don't know if you've had any luck. I was looking to do the same when I fit my Apollo on my 2006 S3 K Series.

I traced the Black/Yellow from down by oil pressure sender back to the engine loom connector on the rail under the inlet manifold. There's no connection on the vehicle side of the plug!

I was debating about getting the bits for the loom plug but decided by the time I've fiddled around it will be quicker to run a new wire all the way.

Cheers,

Roger

I found both ends but there was no continuity, so I also fitted a new wire.
