Front Passenger indicator/side marker ground location

[dinosabella]

Hi all,

Does anyone know where the front passenger indicator and sidemarker are grounded to the chasis?

Both the side marker and flasher feed to the same black ground wire which connects to a small harness that appears to go from the fender to the firewall under the coolant resevoir.

Keep in mind my car is a 77 thus no round ground crown like those found on the later cars.

I'm hoping someone can save me from taking appart the dash!

I had many lighting issues that I worked out this weekend, the rear lights are new, every single gound that I could find was cleaned. Everything works nice and bright exept for the front passenger side flasher. When I turn the 4-ways on or the front pass/flasher, the side marker dimmly flashes.

Thanks!
