Sorry to post here, but got NO response on MD page. I am trying to install the Edge Juice in a 2004 Chevy 4500 w/ LB7 Duramax. I can't find the correct plugs on the wire harness to match the Edge plugs. On smaller trucks, these plugs are on the drivers side. My computer is on the passenger side. I found the smaller plug under the computer but can't find a plug for the larger plug. Several people on the MD page claim to have the Edge unit on their 4500 and 5500 trucks. I have tried to contact them for help but none have returned my email or PM. I contacted Edge and they are looking into this installation. If anyone has any info, please send me info. Thanks everyone, John

It should be on the top of the engine on the drivers side.

Sorry, no wiring on the drivers side. All wiring is on the passenger side on the 4500 Kodiak.

Behind/under the air filter if I remember correctly

FOUND THEM!!! Bless you. You are the first person to help me locate those plugs after asking and PM'ing for the past week. I actually thought I had made everyone mad at me somehow. That or they thought it was such a stupid question. But on a 4500 that huge air cleaner blocks the top of the engine. Plus I thought it would be close to the computer and the passenger side. I hooked it up and played with some of the settings on the Attitude unit. I will wait to start it in the morning. Don't want to wake the neighbors. Thanks again, John

sorry but i have no experience with 4500s

It has been almost 2 years since I installed a Juice box on that client's 4500. At the time the Attitude didn't exist and his was a stick intead of the allison. I had to program it on my truck before installing it on his. I programmed his on level 2 since most of his use was heavy towing.

I remember trying to do this from inside the cab by removing the cover but ended up messing around the air filter canister.

I'm glad that I could help you, mainly on this forum I get help from others...

Thanks again, Got everything installed. Engine running alittle rough but I've been told it may take several days till the computer learns the new programs. You was the only person who would help me. If I can ever help you in any way, just email or PM me anytime. Thanks again, John
