    T87 Swaps

    This is a side question to the purpose of this thread, but here is my question: If the battery voltage is say 12.6, 12.7, why is the control module voltage 11.9/12 and why?

    I don't have 2001 wiring, but here is how you get the 2003 wiring. GM doesn't change tons of wiring from year to year, so this may be good enough to answer your question https://www.gmupfitter.com/wp-content/uploads/2021/05/2006_LD_CKFullSizeElectrical.pdf
