Hey friends, recently my wrx is been doing really strange things in regrards to its electrical system. It all started when a very good knowledgable friend installed Jdm headlights for me lets call my friend Mark. My car was oem boost guage and alarm

I took my friend to do a deal with a local guy (Joe). I paid him $300 plus my oem bugeyes. Joe insured mark and and I that he had run jdm headlights buy splicing the oem harness with out problems.

Mark my friend, followed joes instruction and the swap was sucessful. with in 30min both joe's and my car had working headlights. The only minor problem that the city light, to the right upper corner of the passanger side didnt turn on right away, i would have to drive the car a couple min so it will turn on. Mark and i figured it was because they simply used plastic fastiners to connect the wires. Regardless everything was fine and i was happy with the splice job.

A week later, i took my wrx to marks house so we can soilder everything splice. I did it in hope to fix that stubborn city light. He soilderd everything but he used alota soilder because he only had Thick guaged soilder. Everything worked the same, even the city light that had problems. Then i figured the bulb was going bad so it didnt bother me.

Everything worked fine for about 3months HERES WHEN THINGS GOT WEIRD
I noticed that as soon as i turned off my car, the red blinking SECURITY would flash on the dash cluster. This was weird because, before, red security would only flash once i armed my oem alarm. Another thing is that when arming or disarming the alarm, my city lights would flash and tail lights aswell. Now i get nothing...?

Heres the most annoying problem Extremely loud and constant relay clicking noises. Before, i would get a quiete relay noise when only engaing highbeams.
Now i get a relay CLICK thats extremely audioable, at least 3x louder then stock. I get it when putting my turn signal, turning on low beams, and seldomly when turning on the highbeams. Furthermore, when moving the light bar to the left of the steering wheel slighty forward, i mean barley moving it and not engageing the bar at all, the relays click really loud. and most of the time the low beams turn off and im left with out lights for a split sec untill i stop touching the column at all. Also, the low beams seems to flick off and on occasionally when using my turns signal and turning the wheel while driving at night.

Mark, re-did the soildering job, and used less soilder with a thiner guage of soilder. He told me that too much soildering would cause a Load, so he fixed that and the problems remained the same. We checked all of the fuses, they are all good.

Please help, what eles can i do to trouble shoot? If its the splicing job that causing the problem, why didnt it happen right away? oh another thing, the horn that connected to the passanger strut was left off and the wire melted onto to my helix dp melting the insulation. This happend after the problems arose.

What could be causing all this? How can i trouble shoot it. Could it be a bad faulty switch to the lights that causes this. The loud clicks come from the glove box when im driving and from the fuse box in the engine bay when i was standing outside. Please Help!

ps. My oem head unit turns on and off consecutivley and will not respont to any commants, i pressed every button. It sometimes get stuck on this mode where it turns on and off rapidly. Even if i take off the car, it doesnt fix. right not its normal i think it has mood swings...
