Hey guys My question is if I have a painless harness ready to go in and I am doing an LS swap within the next year How can I adopt stand alone harness to the painless harness so I only have one fuse block?

That looks like a nice integrated kit but kind of expensive. Doesn't include the ecm.
I've used the Painless chassis kits on a number of LS swaps. You really don't need any integration of the chassis harness to the LS harness. Just the 12 volt wire that has power in start and run. Painless techs told me not to run the 12 volt ecm constant thru the Painless fuse block, run the ecm 12 volt constant wire directly to the battery. I just run the 12 volt constant off the starter stud. Most LS harnesses come with a small fuse block (5?), a couple relays (fuel and fans) and a OBD port and check engine light. Its pretty compact. I put mine right behind the glove box. Good luck with your swap. |
