Hey all, im installing an msd ignition (6AL) in on my b18c1 motor. theres 4 wires to install into the distributor. I've got 2 of them installed.

(MSD SIDE) (STOCK DISTRIBUTOR SIDE)
RED -> Black / Yellow (12 volt source)
WHITE -> White / Blue (electronic ignition amplifier output)


But i'm left with 2 others i need to install

(MSD SIDE) (STOCK DISTRIBUTOR SIDE)
ORANGE (+) Positive terminal of coil
BLACK (-) Negative terminal of coil

the screws inside my distributor are being difficult to remove, and with just the cap removed it appears I can't see the positive and negative terminals. Anyone know what color of wires would connect to the positive and negative terminals already, and would it be okay to just splice into these from the outside? If not, where are these terminals exactly?
