So, I bought someone else’s headache.
2005 LJ with a 5.3 from an 07 Chevy 1500, Turbo 350.
Everything was great when I bought it, but it soon started acting up. I won’t go into all the little details of the issues it is having as they could be a hundred different things, but if I could put a scanner on her it would help a LOT.
The problem is that they used the stock 5.3 computer and just wired it in to the jeep WITHOUT a OBD port.
I need to decide if I can wire in a diagnostic port to help me track dow nthe issues or if I should buy a wiring harness made for the application.
It is a turbo 350, so no electronics there. The gauges are not the factory ones for the jeep, so no issues there.
