Im wiring a Ford type solenoid from Napa (part# ST81) on my BBC. Its a 4 post top two large post ones Bat and ones Start. Bottom two small post ones Start and ones Ign. From the wiring diagrams i've seen around here I have a good idea how its supposed to be wired but if I run my Alt, power and both battery cables like the first diagram below they wont all fit on the one post. Is it ok to use the 2nd diagram as it seems much less cumbersome, or is that a different solenoid then the ford type I have?
