Custom engine harness, NEED HELP

[04blackmax]

I have an 04.5 LLY, it's got twin chargers on it and i want to build my own custom engine harness so i can move the FICM for piping clearance. I talked with a local GM dealer and they said they cannot look up the part numbers individually, they want to sell me a whole new engine harness. They also said the service department gets a tackle box of terminals for repairing harnesses directly from GM and they are not authorized to sell me one or even let me look at it. I am after Part numbers for the terminals on the engine harness. I need all the terminal and seal part numbers but any numbers you can help with would be awesome. Injectors, ECT, Oil temp, cam, crk, FCIM, ECM, etc.....Thank you in advance for any info you can provide

:nail:

Try to contact Ben @ BTDieselworks. He has a lot of terminal connections and advice on how to lengthen a harness.

I have 45 GM terminal boxes. Get the part numbers you need and I should have them.
