headunit issues

Don\'t use the aerial as the ground. If your existing wiring doesn\'t have an earth wire, attach it to a metal part of the car.

Also, check the fuses in the engine bay. The interior fuse may be blown.

But definitely make sure you are using the correct wire for the constant +12v and the switched +12v. This will be what is causing your memory issues.

+1 swap em round and with the fuse replaced it should go. Easy way to check if you have a multimeter or test light is with the key off the yellow wire should have ~12v(multimeter) or the testlight should light up with the key on or off, that will be the batt wire which will let you keep your settings. Repeat same with the red but when key is off there should be 0v/no light, thats the acc. Hope you sort it

What car is this for? And head unit? I could swing by one day next week and compare wiring.

For a friends gen 1 legacy, jvc unit. For some reason the constant 12 isn\'t constant and can\'t work out why.

Are their speaker wiring the same as the WRX\'s? My head unit is Pioneer though :S

      Afternoon team,
      im new to the group first time posting. Im hoping some body can help me get my launch control all dialled in on my link g4x. Ive had the computer and car all tuned from chris at prestige awesome knowlegable guy super happy with the results but now im wanting to get my launch/anti lag all dialled in. Ive been reading multiple different forums etc all with different conflicking information which has made me nervious with what do i listen to this or that if you get what i mean. Now ive started to make myself familiar with my PClink software etc the past few weeks and im eager to learn how to do minor setups or tweaks etc so im not relieing on my tuner so much and obviously saving myself abit hurt in the back pocket. 
      Now back to the question at hand.... Im wondering if theres and one who could please share there knowledge and wisdom with setting all my values, timing, fuel etc when i have launch control armed and engaged, or even a launch tune file they can possibly send me to load onto my tune. Ive figured out the setup of my digital inputs turning launch control on etc and its obvisously on its pre set factory settings. It engages but doesnt sound the greatest or as angry as it should i feel. Hence reaching out to you good buggers. 
       
      Cheers in advance for any info and help yous maybe able to give me.
       
      Cheers Shaun
