Building an LT5 engine harness from scratch. Any advice?

[shanker]

I chose an Autronic SM4 programmable ECU for my LT5 powered '62 corvette build. I purchased all new delco connectors for the injectors and all sensors.
My engine is a '92 and I have the factory GM service manual as a guide, but I'd like some more detailed wiring information for the connectors. I can't go by the factory wire colors, so I need detailed labels for each pin on each connector. Is there another book I can purchase? I've seen an LT5 engine controlled with this ECU so I know it's been done.

I may be in over my head on this one! Let me know your thoughts.

Thanks in advance.
