Ok Guys.. i might be posting on the wrong forum. Im new to cobaltss.net.. so let me know if its not right.. I accuired a 07 cobalt ss/na 2.4 le5 w/5 speed manual and the block cracked after 6 months of driving.. so i just purchased the 2.0l lsj supercharged to drop in with the limited slip diff manual 5 speed tranny and everything has been going well untill i hooked the ecu up.. My problem is connecting the new ecu. 2 out of the 3 plugged in no problem but the j1 blue connector is a different plug than what is wired in my car from the le5.. i have the j1 plug that came with the new engine and ecu but its deffinitely different than what is wired in my car now. and definitely more wires than the le5 connector has. can someone please lend me their expertise.. i need help with wiring in the new j1 so my new ecu will work.. please help me guys.. a wiring diagram between the le5 ecu and lsj ecu would extremely help. i can do the work myself as i am already the one doing the engine swap..
