Hey Guys Im almost done my Metro JTM45. I am stuck at Step 8. I'm supposed to tie the Black PT wire with the Black wire from the amber lamp. The problem is that I dont have any Black Wires on my PT.
I got this Tranny from George and his Kit...

The Model is a JTM-45-E Heyborer PT. The color of the wires are :

PURPLE
BLUE
RED
ORANGE

No Black Wire. Im guessing these are diff voltage taps. Does any one know what thes wires are? I want to finish this amp today!!!

I have included an exerpt from the Step that Im at...

Thanks
