I'm at a loss looking for the chassis ground for the turn signals. I found the one to get the fog lights going and the one that kept it from starting. I can't find the one for the turn signals. I can ground the bulb housing and they work, so I know it's a corroded ground. I found one on the front and back of the head on the passenger side and one on the VAF and one in front of the distributor. Somewhere there much be another one. HELP!
