Well I have relays for just about everything that goes thru the ignintion switch...
I almost had a heartattack when I realized that the lights in the 75 didn't have realys in the circuits, ALL the amps went thru the stalk..
The improvement was amazing.
Did the same thing to the Alfetta and it was such a big difference I had to check the bulbs, thought they were a higher watt rating then legal.
Highly recommended.
