1977 Baywindow, 2 liter, Fuel Injected.

I installed new LED bulbs for my parking/brake, backup, and turn signals.
Lighting is MUCH improved.   I even added silver reflective HVAC tape on the
inside of the light boxes.

All work well, and the turn signals blink rapidly-as I pretty much  expected
they would.

Suggestions on thesamba was to install a 470 ohm resistor to cure the
rapidly blinking turn signals.      What is the easiest way of doing that??
I thought about adding a resistor, inline between a male and female spade,
and then patching that in right at the turn signal.   I am thinking that it
has to be done on both sides?     Electrical is not my strong point-and I
may be totally off base, so don't laugh to hard.

Any suggestions.

Thanks
