ECU Ground

[bigap15]

Where does the Ecu ground in a 94-95 mustang gt. My LC1 is reading wierd, so I want to ground it to the same ground as the ecu. It says in the manual to do this if you are logging through the ecu, so each ground isn't difference for accurate results. I will be logging afr through the egr wire. Thanks

Is it the small wire that goes directly to the battery, or is that only for the ccrm?

NO. The ECU is grounded to the chassis behind the passenger side kick panel. To the OP. The correct answer doesn't change by asking the same question in different forums.

Didn't know I wasn't allowed to ask the same question in a bunch of different forums, to get a quicker response. Next time I will just pm you personally since you know it all. Thanks for the response tho.

I was just being sarcastic. I've wondered over the years why posts are made at the same time on multiple forums. The quicker response hadn't crossed my mind. When I post a question I usually select the forum where I think I am most likely to get responses and a solution. If after a couple of days there aren't any replies or very few I'll try another. Maybe that's just me. In any event, I apologize for the flippant remark
