Re: My swap. 5.3 into a 1990 3/4 ton 4x4 Suburban.
In honesty it confuses me too! All i really did is disconnect the computer connectors and drag them the through the hole in the fire wall, then went through them one by one while looking at a pin out diagram that described what each wire on each connector was for, clipped out the ones i know i need to keep, and through the rest away.
