glow plug relay issues.

so I was mussing about under the hood of my TD yesterday. wrapped up, and went to fire up the car- no glow light. Thinking it could be the bulb, I cranked anyways and she did not fire off.

so I grabbed the test light- fuse strip is good, got power to it on both sides.

all 5 GPs are less than 2 weeks old bosch units. all test good.

relay is not kicking on, and I swapped out w/ a relay which was working fine on another car last year. same issues.

with the testers I am not getting continuity to ground to the brown wire on the 4 wire plug.
I get 12v+ to the #1 on the plug, or term 15 on the relay. red/ striped wire.


anyone know where the brown ground wire ends from the relay ?( where is it grounded to??)
from what I can make out of the other 2 wires, one is the violet wire which goes to the NSS, the other is to the light in the dash.

should I get hot from the violet wire? or only when key is turned?
