vehicle wiring products they have pins and connectors and as for ecu multi plug get down the scappy and find a sierra with abs this has the same type of plug on it one by one swap the wires over(job done)

A babyboard is needed in a level 8 ecu std or pectel its something the do with extra functions and on a pectel its encrypition

if you have a std one keep it there usefull as the main tuners use them now for upgrades ie MSD and RPlabs
