The CTS-2300 (to 1975 all scout, light and medium trucks) specs RJ-10Y for a
scout with the 345 and a J-10Y *or* RJ-10Y for 100,200 series pickups (all
vehicles, this only applies to 74-75 as it is for the gold box ign.  I don't
have time right now to see what it calls for for the points systems in
light, medium and heavier trucks.

I do also seem to remember that my 78-80 Scout manual also lists plugs for
loadstar applications in the ign system.
