Hazard/Gauge issues

[Ford Fester]

So I have some wiring issues I think. The turn signals don't work up front. When the headlight are on bright the defrost and turn signal lamps in the dash are on and dim. When the flashers are turn on with or without the headlights on the tach, bright signal and defrost lamps flash and bounce. And ideas where to start?

Grounds

x2 If you have bad or dirty grounds, weird things happen.

There's a multi-pin ground behind the battery box that might be the most likely culprit.

also look for the main dash harness ground near the ECU.

Cleaned grounds still same issue.

any missing grounds after the wire tuck and battery relocation?

Good call. They are easy to miss.

What about the groundingblock behind where the stock vaf is? It gets over looked. Another culprit could be the headlight switch. I've seen them do some funny things.

Time to start wiggle testin

i ground what was grounded before. The only ground i know i eliminated was the one on the right side from the cylinder head to the strut tower.
