The best way to fix these, IMO, is with a secondary cable from a later machine, where the pins of J115 are all home-runs to the transformer instead of looped.

Couple ways to accomplish this...
Easiest way, but costs more:
Ask Jim Shird to make you one. Either a complete secondary harness, or just the transformer output to J115.
Cheaper, DIY way:
You could convert the one you have, out of the game, on your workbench, pretty easily.
You'll need some .093 crimp pins, some .156 trifurcons, most likely a new housing for J115, keying pin for the new housing, and some wire.
Remove the entire secondary harness from the machine
Measure the existing wire from xformer to J115, the wires should all be about the same length. Add an inch or two for wiggle room. The parts breakdown for Dirty Harry specifies 47 inches *per run* - but you need 2 runs for some colors
BAA sells the 'right' wire to get the colors original and everything! For this application, you want 18 gauge wire.
HW-30018-49 - Yellow with White Stripe. You need 47 inches
HW-30018-91 - White with Brown Stripe. You need 94 inches (2 pcs, 47 inches each)
HW-30018-1 - Brown wire. You need 94 inches (2 pcs, 47 inches each)
HW-30018-93 - White with Orange Stripe. You need 47 inches.
HW-30018-5 - Green wire. You need 47 inches.
HW-30018-94 - White with Yellow Stripe. You need 94 inches (2 pcs, 47 inches each)
HW-30018-3 - Orange. You need 94 inches (2 pcs, 47 inches each)
It comes in 10 foot lengths for about $3 per color. A 10 foot length is 120 inches, so 10 feet of all 7 colors will suffice. Yeah, it's $21 or so, but that's just a few LEDs, right?
Cut the wire into the 47 inch lengths, and put a .156 trifurcon pin on one end of each cable.
In the case of the 4 wires where you have 2 47 inch lengths (orange, white with yellow stripe, brown, brown with white stripe), strip the ends of those wires, twist them together, and carefully crimp them both into a .093 pin.
In the case of the other 3 wires (yellow w/white stripe, white with orange stripe, and green), crimp the single end into a .093 pin.
If you take your 03-09-2092 molex connector housing and remove all the wires from it (or start with a new one, preferably), you can turn it sideways so the 3 'teeth' are facing to the left. The top left pin is pin 1, bottom left is pin 3, top right is pin 7, bottom right is pin 9.
Pin 1 - White with Brown Stripe (pair)
Pin 2 - No Connection
Pin 3 - Brown (pair)
Pin 4 - White with orange stripe
Pin 5 - Yellow with white stripe wire
Pin 6 - Green wire
Pin 7 - White with yellow stripe (pair)
Pin 8 - No Connection
Pin 9 - Orange wire (pair)
Then, take a new 12 pin .156 housing. Insert a keying pin at pin 9. Insert the wires as follows:
Pin 1 - Yellow wire, white stripe
Pin 2 - White wire, brown stripe
Pin 3 - White wire, brown stripe
Pin 4 - White wire, orange stripe
Pin 5 - White wire, yellow stripe
Pin 6 - White wire, yellow stripe
Pin 7 - Orange wire
Pin 8 - Orange wire
Pin 9 - Key
Pin 10 - Green wire
Pin 11 - Brown Wire
Pin 12 - Brown wire
