[Vwdiesel] Hazard/Rear lights grounds

[Kneale Brownson]

Are there other grounds to the 1994 Jetta tail/brake/hazard/turn signal lights than the one at the driver side rear fixture and the two on the rear fenderwells?
 
I cleaned and dieelectric greased all those a year ago and I'm having  the crossed signals action (brake lights blink alternatively when turn signal activated) and green blinker in the dash lights when I step on the brakes, etc. problems again.
 
What a wiring marvel these VWs are.  Even worse than the Audis I've been driving the last 20 years.
