Rob,
will it be ok to join the sensor ground wires at the ring terminal point?
im doing a loom for stuball's v8 capri (dnb doing ecu),
at the ring terminal point it will be where i go up to 6mm cable to run to the back of the head,

or do i need to run the sensor earths direct to the vems at pin 26? (as you say the 20mm up is not needed)
also i see on the wiki (your post) you show this,

where do i need to do this? or where i do the solder join to 6mm be ok?
