Changing the original 307 to a 71 Olds 350. The 307 starter only has 1 small wire post, (no markings) where the 350 starter has 2 small posts (1 marked S) (1 marked R) I know where the large battery cable goes, but my wiring harness only has wire for 1 post. what do I need here. The starter was from a 69 98 Olds 455. Don't think it matters but since the 350 has higher compression (10.5-1) thought this starter would be better than the 307 starter.
