PCM Diagnostics & Tuning - Ls376/480 Diagnostic??
05-01-2012, 08:58 PM
This may be the dumbest question ever, but I haven't been able to find any info on this site or anywhere else about it. I have an ls376/480 crate motor and controller kit in my project car. I have the engine wired up and have started it, but I want to look into changing the fan on/off temps and I cannot find a diagnostic link connector anywhere on the harness. The manual says it is in the fuse/relay box but I can't find anything and it's kind of confusing. I would appreciate any advice if anyone knows much about these crate engine computers. Thanks!

The diagnostic link connector is wired into the same cable that goes to the throttle pedal. It shoud branch off just before where it plugs into the pedal.

Thanks John! I will look there next time I'm working on the car.
