Every connection on my JB4 is connected. So you're saying one of them should not be? It's hard to keep track of all the different guides and updates...do you have a link to this guide? Thanks!

Click on the F10_n55 pdf to download the latest installation guide. The only harness you don't connect is the purple one.

alright thanks for the help! I disconnected the MAF sensor and hope this does the trick.

Looks like this did not do the trick. Getting the battery drain warning every day still.

Never once had this issue prior to installing JB4. Pretty annoying. Any other ideas?

Any new firms out there for the jb4. I haven't seen a new firm in a long time?

Yes, I talked to Terry via email and he said it was not a known issue. And that was that. Maybe it's just an unknown issue.

Sorry to hear about that Ben. Make him give you trade you for a stage 1 and the difference. That sucks!
