Had this posted in general for a while and was advised to post here so here goes...

I dont own a cobalt but do have a lsj out of one (06 ss lsj 2.0) and am in the process of putting it in a toyota rock crawler. I am stuck finding some info so I have come here seeking some cobalt ss/LSJ wisdom.

First, Is there a part # for the coil harness or is it considered part of the engine harness? I have seen pics of the harness with a GM PN tag but my local dealer says it's all part of the main harness.

Second, Is the gas pedal connected to the engine harness or dash harness? Is there another short harness that goes from the pedal to engine bay?

Third, Who would you recommend I use to flash the ecu to get rid of the vats and all other not needed functions so it will run in my truck?

I hope you can help me figure these things out and probably many more questions in the future and hope I am able to contribute as well.

Thanks

 

yes there is a coil harness call tom at ced 1800 441 5150 anyone with a clue can reflash your pcm and the pedal is not part of the engine harness it is part of one of the harness that runs to the pcm from the inside find a wiring diagram that will tell you

 

You could use hptuners to flash the pcm.

 

I have a couple sets of coils with harness attached, if you can't find one I can see if they have a part # on them. Or if you want a used one i'll be happy to sell one.

 

Go to this link and you can download the PDF's that have all the part #s

Awesome! I knew the info was there. Italian joe1 I would like to get a harness from you if the price is rite but I need a few other things my motor is missing and would like to pay to ship it all from one person if possible so when I get my list ready I'll pm you for sure.

As far as flashing the ecu I'm not sure if I really need to get hp tuners since once it runs good I'll be done and have no need to keep tuning. I would like to find someone who knows exactly what to do and have it done if I can get some recommendations. I have been looking local (Fresno CA.) and it's obvious I have not found the rite person yet... Sooooo any recommendations?
