I feel foolish, but I am not sure what this relay is for? I have a new American Autowire harness but this plug and relay aren't called out in the manual. The car is a 70 Elco, 350/350, it had factory AC which I have removed and it's been three years since I pulled all of that out so I'm a little fuzzy.

I am old and so is my brain,,, I think its the T.C.S. relay. It should mount on the wire gutter on the fire wall with two smooth head rivits. :nerd: You also may have some wires that go to the T.C.S. on the intake manifold, WHAT? When your 4 speed is in fourth gear and or your auto is in third, The relay on the intake controls the Vacuum to the dist...... OH ,,NO more Sh!p to deal with! :surprise:
Check the wire colors on the wiring drawing.
