Thread: Any Fellow Rodders With Fi Harness Knowledge?

Tweet

I wanted to go with a LS2 but I'm leaning toward a LS1 now.

Does anyone know the direction I should take with the fuel injection harness?

I know that I'll have to have the ECU reflashed to rid of the security and add the specific data (tire size, etc). I also know that Street Performance makes a harness as well as the myriad of others out there (Painless) that also makes them. But good grief.....a $1000+ for just a wires?

I'm guessing everyone will suggest that I get a wiring diagram for the specific year and modify the existing harness myself.

I was just hoping that someone out there did that for less? I'm not real savvy with fuel injection. This is my first build.

Anyone?

buy the harness from street and performance , 4 wires to hard wire in the car
red to battery ,red to key on , black to ground ,and brown to fuel pump relay . the rest is plug and play .

harrison , arkansas i know where thats at .

Just installed a unit from Affordable Fuel Injection, nice stuff for the price....

Thanks everyone! I appreciate the feedback.

Man...my head is swimming.....

Just trying to get the most for the dollar....which is starting to lead me away from the LS toward a bigblock/700r4. Maybe a reman 427 or 454. I might buy a fuel injection kit (like and newer Enderle style) for it later when dollars permit. Right now...I'd just like to decide for sure what block I'm using so I can get started on the mounts/frame Xmember etc. Once Ive decided....it will be set in stone so I wont be a pest......LOL's.

Really thanks!
