Default 06 WRX, Brake land abs lights constant, No headlights, intermittent drls

06 WRX.
BRAKE light is on no matter what position the hand brake is in.
ABS light stays on constantly.
Fog lights do NOT work.
High AND low beams do NOT work.
Auxilary engine fan AND running lights come on when I put her in REVERSE.
(goes off once out of reverse).
CEL on intermittently and clears itself randomly as well.
My fan oddly enough turns on any time I have my running lights active. If I put my e brake down after starting the engine, drls illuminate. If I pull ebrake again, they stay on unless I turn my headlights into the "on" (which doesn't activate headlights) and back off. Also my fuel economy seams to have decreased.

This all happened after messing with the harness/module associated with the "DRL Delete Mod" under the passenger dash. If anyone has any information on that harness and module (nick named the drl module although it appears to do a lot more than simply activate drls) it may be helpful as to narrowing down the issue here. I have a feeling something in the harness shorted and fried something but I do not know what the module works in conjunction with.
I have cleared the code, and also done an ecu reset. All fuses check out to be fine. I have also swapped the drl module with a friend of mine and no difference was made.
Any info as to what this module works in conjunction with will be handy as to narrowing down what may have been affected by a surge or short from the harness wires

The CEL Code is a P0607 Control Module Preformance
I appreciate any relevant, valid and helpful input.

This is a pretty weird one.

Since the warning lights are tied into the alternator field circuit lets see what happens when you disconnect the plug on the back side of the alternator and then start the engine. This will of course disable the alternator but lets see if that changes some of the issues. If that helps then the alternator may need to be replaced due to excessive AC ripple output. If that doesn't help then I suggest you check for a bad ground connection from the battery to the chassis under the hood.

Thank you very much, I will do that and keep you posted. I would still appreciate any other input from you guys!

Ps, the code cleared after resetting (obviously) and has not shown up in the passed 180 miles, however all other issues persist.

Unhappy Issue diagnosed.

It is now that I write my somber report on how my appointment with the stealership went...

ECM/ECU needs replaced... 860$ with labor. ECM is over powering a few channels by 100%, it's reeding an output of 2v when it should be putting out 1v.

In light of this info, does anyone have any suggestions as for my next steps?

Should I:

1: Pay for and have them fix the issue?
2: Buy a used ECM and roll the dice?
3: Buy ECM from the dealers and swap myself?
4: Or is there anywhere I can go to have my current ECM diagnosed and repaired?
