barge Posted November 30, 2020 Report Share Posted November 30, 2020 Doing a search it looks like the older ECUs had a convenient spot on the board to power up the PnP ECUs. I've got a WRX104 g4x coming that i want to power up on the bench so I can get that software dll issue resolved so that I can get my tune all transferred over from g4+. Is there a convenient spot on the g4x board to do this? or should I just power all the appropriate pins at the header? Quote Link to comment Share on other sites More sharing options...
Brad Burnett Posted November 30, 2020 Report Share Posted November 30, 2020 Id just go to all the appropriate pins on the header. But its typically just 1 or 2 pins that need power. Ill check my notes when i get home, as i have made bench harnesses for 02-05wrx and 04-07sti. Quote Link to comment Share on other sites More sharing options...
Adamw Posted December 1, 2020 Report Share Posted December 1, 2020 You can use the TVS diode as per your other post. Quote Link to comment Share on other sites More sharing options...

Wasn't sure if that would get buried over in that section. I ended up using I think B6 and D3 on the header and that worked just fine as well.

koracing Posted December 2, 2020 Report Share Posted December 2, 2020 This always works - TVS diode. I wish it was this easy powering up the wire-ins. Quote Link to comment Share on other sites More sharing options...
