Bruce I have a 2001 5.7 GXI and my DLC had I think 6 pins. I think the manual had me jumper the black wire to the white and black stripe wire to get in the base mode. I used my old Sears pensky timing light that does not have advance. 8 deg advance = 5/8" to the left of the crank timing slot. Someone here posted the procedure for me. Dave-R
