Can anyone confirm that this is the ELD wire A30? This connector is the closest to you when looking at the ECU. The wire is green and red. Thanks.

 

yes... first connector near hood release ---a30...thats what used for wideband hook up.. i would verify color but im color blind lol.

 

Thats the one I spliced into, but its in a different place on my 07.

 

Where do you guys splice the ground wire for your widebands?

 

Put a ring terminal on the ground wire and use one of the bolts next to the hood latch release. The wideband doesn't need to share a ground with the ECU.

 

This. Seriously. I've done the ground on my wideband a couple different ways, and all of them resulted in a 'travelling ground' which basically means that the voltage varies slightly, so my wideband would be on sync sometimes and then sometimes be .2-.3 off. I changed the ground to one of the bolts like spectacle is talking about and that issue went away.

 

Spec-

Can you verify you had to remove some resistors on-board with the Kpro to get the PLX wideband to read below ~11.5?

(Appologies to OP for thread jacking)

Thanks!

 

Yes I can verify. This has been verified to apply to the ELD wire...if you use one of the analog inputs (KPro 3), you will might not have this problem.
