LS3 Wiring Diagram

[ModernMuseum]

I have a L76 crate with an LS3 top end (and a mild cam) that is going into a 69 firebird.

Can someone help me out by providing this diagram? I pulled the following information off of the ECU.




On the ECU, it says:

GM Racing
GM# 19258268
Gr. 3.670
GM Performance Parts LS376

It's wired to mate to a T-56 Transmission

With the harness is a pretty hefty fuse box. I couldn't find any telling ID numbers on the fuse box. It has four relays, a couple of 50 amp fuses, a couple of (i think) 30 amp fuses, and a bunch of ancillary fuses. (I'm trying to mate this harness to a Painless harness.)

After being left out in the sun for a few hours, it appears the paper inside the fuse box has faded, rendering it un-readable. Does anyone have a photo of this?

PM me with your email address. I have a .pdf wiring diagram that might help if you're patient.

Any chance in you sending me that diagram as well. I have a LS376/480 GMPP harness kit & the fuse diagram under the cover came faded.

Sure, PM me your email address.

Does anyone know how to take the PCM/ECM connector housings apart to add/remove pins from it? I want to add one for the reverse lockout but haven't figure out how to get it apart.
