Title: Which post is the "s" terminal on the starter?
Post by: xtremjeepn on June 24, 2007, 12:16:48 pm

Wiring the trail clean up truck with the "Painless" wiring harness.

There is a big red wire that goes to the big post which also has the battery lead to it.

Then there is a purple wire that is supposed to connect to the "S" terminal. I have 2 terminals left on the selonoid and I can't find an "s" maked on either one. So which one is it? The one closest to the engine? Or closest to the headers?

For reference the motor came out of my 74 and is a 454.

S is closer to the engine. R is closer to the exhaust. The S terminal is the command signal to the solenoid when you are in the cranking position. R is used for full 12volts to the coil in points ignition systems and nothing will go there if you have HEI
