I have a couple questions I have a vps and pfc fcon it has 3 wires blue green and yellow is that supposed to be for the gm 3bar maff sensor? 2nd I have the vpc but the vpc is from an 89+ how can I wire it in to my fcon jumper harness? Id appreciciate all and any info you could provide me! I figure the vpc only has 5 wires can't be that hard.... I found wiring diagrams in PDF format but they don't show any hard wire diagrams just the plug and play jumper harness stuff so I did do some research just throwing that out there before I get flamed lol
