Default 8381 msd opti for 92-94 and 92 corvettes

if you have 92 vette you have to solder the wires together; the harness is different for 92 only
you connect as follows
gm msd
a 1
b 2
c 3
d 4
the fifth wire used only in 92 is just a ground for shielded cable
this is the info that msd gave me and it works
thanks pedro estrada jr from msd for getting back to me

thought i'd post this for anyone else with 92 vette
car is back together and so far runs well
hope the msd opti lasts longer than the oem stuff

a-----blk/red 1—brown/yellow----low res

b-----ppl/white 2---brown/orange-----hi res

Can anyone share with me the part number for the female connector that will mate with the MSD 8381's male connector?
