I would like to put a SunRay S-12 on my older Excal 1000 with the Blue decal 4 wire setup ? ....Has anyone done this mod SUCCESSFULLY ? .......Can you tell me what wires on the Excal go to what pin number on the S-12 ? .........I called Ralph, and he cannot tell me as he does not make this coil ....he sells them .......I was wondering if anyone can tell me this info that has done the mod ? ....I can find info on the SEF and the WOT , but not on this coil .....Thanks, Jim
