Before proceeding, I would like to offer a warning
to those considering, or attempting to connect an MSD 6A to their StarQuest.
Initial research, (and a letter to MSD technical
staff) discovered the MSD does not support the installation of their 6A
to the StarQuest. Reasons of incompatibility with the ECU were given,
and stern warnings the the MSD technical staff had destroyed a ECU (a rather
expensive mistake..) in their attempt to connect the unit.
Fortunately, I did not know any of this before I
installed my 6A, and had no trouble at all with making it function! ( And
function very well, I might add! )
In fairness, it may simply be that I got all the
wires in the right place the first time, and did not experiment with the
other possible connections.. Also, it may simply have been ECU model related...
The compatibility to our cars is still debatable,
but so far I have yet to hear of a fried ECU while using my wiring diagram.
But again, almost everyone I have helped is running the latest ECU
Part Number MD120197. This ECU was most common beginning on production
date 06/87 until the car terminated in 1989.
Again, MSD says it can not be done, yet several
have experienced success...
As you can see, the decision to proceed is
in your court, and I will not be held accountable for your decisions.
