Hello everyone
I'm working on my 72 510, just did a l20 swap out of a 77 truck and Im trying to install the Transistor ignition unit to keep the motor as it came from the truck but I'm not sure where all the cables go. transistor ign unit has five cables, black, green, red, blue and black-white. I have installed black to ground, green and red to distributor but blue and black-white not sure how to install them. can anyone help?

Distributor wires are Green and Red (G and R)
B goes to a good ground, either engine ground or body ground.
Black/White goes to Coil positive
L (Blue) goes to Coil negative
