Dash lights and gauges out

The round canister is a noise surpressor.

RedFish has the voltage limiter. He can also disable the mechanicle limiter in your gas gauge.

I had him do mine and I'm running his limiter with no issues.

I am as well. Nice unit and simple to install.

You know, NOS is fine, but keep in mind it will also not eliminate any
original design flaws. The technology we have today was not available then.
I am suspect of ANY electrical parts that have been stored for
40 years new or not.
