Also, How many wires are there in the harness before the term block? Should be 7 or 8.....
#1. Red/Pink 10ga (Constant Hot)
#2. Black 14ga (Ground)
#3. White 10ga (Start Solenoid)
#4. Orange 10ga (hot for alt. and amp gauge, not used if running volt gauge)
#5 Purple 16ga Ignition hot (Key on) For dist. or elec fuel pump
#6 Gray 16ga tach signal
#7 Blue 16ga Oil press signal
#8 brown 16ga Temp sender signal
My numbering order may differ from actual diagrams, but you get the idea.
