I've just finished wiring up my interior and when the turn signals are on the dash or gauges seem to dim out abit with each click of the turn signal. Also when my lights are on the rear brake lights dim as well with each click.

I know there are a few wires I've yet to ground so would this be the problem?

Cheers

 

yes.

 

I agree. Ground wires are very important.
