I have an LQ4 in a 2002 sierra denali. It is the original motor and harness. What is the name of the injector connection do I have? Also, what oversized injector can I use that is a direct plug-in not requiring adapter plugs?
Thanks

 

If your going with a Procharger get yourself some 60's. I just did the swap this weekend with some siemans Deka 60's. They are the car style so you have to change the harness. Its really an easy install. only took 2 hours to get it all done. Think about it

 

They are the small little square plugs. I am not sure of the type. I just know they are not ev1 or ev6 type. Only person I know who sells a plug n play 60# injectors is SRT10KILLR. I'd pm him for info.

 

Thanks

 

A lq4?? didn't the sierra denalis come with the lq9's??

 

I don't think the LQ9 came out until 03.

 

I have found "multec 2" as the connector. Everyone lists either EV1 or EV6 as adapters. I guess only Delphi injectors can be plug and play.

 

The 8.1 Marine injectors are the only plug and play for the trucks I'm aware of. They are 42 lbs I believe. They are what comes in a MP112.

 

Fuel Injection Connection can resize your stock or get you rebuilt stock types and flow matched. They just did it for my Vette for plug and play other then adjusting the tune.

 

The last I knew FIC could not resize the delphi injectors that come in the trucks, I would not ever go that route anyways but I was just curious so I gave them a call and asked one day awhile back.
