Hi 28Tudor . . . . 1st off - - - a Very Nice Truck .
Great build from start to Driving ; and for one of the best "Causes"...…
your Dad , good on you.
Ok . . . this is just info : I have installed all LED lights on my
Nova ; installed a 'NAPA flasher # 262 , it made my lights work.
But, they would flash 'kinda slow' . . . then, I found this Flasher :
….. AUDEW LED flasher (and its adjustable - rate)
https://www.amazon.com/dp/B011BTMDQM...novasitecon-20
(better that adding 'load resistors' , to your lights) . . . and, for my LED's
it solved my issue - - - could work for you also, and may be just that simple , as changing your flasher (instead of messing with your wires).
Then, it's cheap enough . . . (was # 12.00 , when I bought it).
Here's my point - - - works great - - - and, I never adjusted a thing
just install . . . like 2 years ago . (I like things that work as
advertised) .
again , very nice truck & . . . . . MAN, it was HOT in Scottsdale on th'
4th . . . . Have a nice day & stay safe …………….
