Just collated some info

looks like it comes through 3 wiring combs, and they are a pig to work with (usually taped up in the main loom)

i will see if there is an easier place to get them from

What radio do you have ? Does it have Bluetooth and USB ? or just an AUX socket on the front ?

Mine is non bluetooth. Poverty spec so just the aux input.

Can anyone help me in locating where I can pickup the tacho signal from?

I do not have the plug in my 2013 wiring loom and have no idea what or where AC2 is or DLC - Pin 9 tach signal

Hoping some one can point it out to me a photo would be great

DLC (Data Link Connector) aka OBD2 port

Ac2 is on the drivers side up high, it's a dash out job to access

Please ignore the TS and CG labels

Hey many thanks for that I will have a look at the OBD2 port to see if the wire is there and piggy back onto it
