Talking to an auto parts dealer is of no use if you don't have a car make,
model and year, so I toured the junk yard and found a, I think, '91 chevy
GT with individual coils mounted on the spark plugs.. They about six inches
long and a lot smaller than coils that I found on Dodge and Ford  trucks,
Nissan and Kia cars since I needed four of them. Now,all I have to do is
figure out what the four pins do and fire up the ADIS-4 again.
