Fuse block & relays are ready wired in my obd2 port also so I can hopefully run gauges on iPad while I buy some nice ones, I’m leaving the wires in the harness ready to wire into gauges. I found out the “Dorman” fuse block that lt1swap shows is REALLY cheap quality. I went down to autozone & got me a 5 fuse version they sell. Has lid to protect fuses & it uses plugs instead of direct solder to fuse holder.
Mil wire for check engine light & the ignition/12+ wires from pcm also need a bit of help figuring out other than that I’m ready to drop in this baby 4.8 !!!
