your issues is that you've got a caveman spec loom in your saph and you've got a sierra spec loom for the vss and a granda spec loom to hook it into

if it was the 4wd version it's easy, but on the 2wd version it's much more difficult

i've looked at both the granada loom and the sierra loom (for the cossie granada and the normal sierra) and while i can find the vss (it's apparently numbered as plug no 238 )it's not on any of the diagrams i can see

i haven't got the old school wiring loom so i can't find that one

don't chop the plug as you may be able to unpin the pins and slot them into the correct plug if you find it
