Which plug for speed/reference sensor?
 

The engine wiring harness I am putting in my to be spec car does not have the speed and reference sensors labeled. How do I tell which plug goes to which sensor? I am not smart enough to understand exactly what it says in Clark's garage explanation.
Its a 1984 harness.
Thanks!

they should have a b and d marked on them match them to the trigger bracket...or just plug them in if the car doesnt start switch them lol

You have a 50 / 50 chance of getting the plugs right the first time around. Watch the TACH Gage Needle when you try to start the engine and if you get a 1/16" needle bounce you lucked out and the engine should start. No bounce, swap the plugs around and try again.
