So I am installing a HALO system into my '14 Ram and ran into a problem. I don't know if it's the system or if I screwed the wiring up. I have a few of these so I don't have to cut my factory harness and I can go back to stock at any time. I cut it in half. I plugged the male into the OEM harness and tested each wire as to its function (Ground, turn/brake, and park). I then looked at the wiring instructions from Whelen for the HALO system and deciphered their diagram (and this is where I may have messed up). I connected the male to what I believe are the correct wires on Whelen cable to bring input into the HALO system. I then connected the remaining three wires to the female 3157 connector and plugged in the bulbs. Did this for the other side as well to complete harnesses. I wired up the control box and connected it to 12v. I turned truck on, turned on parking lights and 4 way flashers. Went to back of truck and had nothing. I reversed the male connections and still nothing. I reversed the HALO bulbs and nothing. I connected the control wire to turn the warning function of the system on. Went to the back of the truck and had very very dim warning lights. Barely noticeable.
The first pic is the 3157 harness I got. The second is how I have it connected.
Here is the install guide.

Is it the wiring? The control box? The bulbs?
Thanks
