Starter Relay Problem- 240z

Well I tried installing a relay for my starter today with no luck. I followed the directions I found on the forum.

87: 20A fused line from (+)

85: (-)

86: ignition switch wire on solenoid

30: To signal wire (original wire that went to solenoid

I tried three different relays just in case; Ebay no name, DEI, and Bosch.

I checked voltages and was getting fine readings. I disconnected everything and reconnected the signal wire back to the solenoid to see if the starter still worked. Worked just fine.

I'm not sure if this could have anything to do with it, but I installed a new starter switch and noticed the previous owner did not connect the two wires from the switch. He just had it plugged into the socket. So I did the same.

I'm not sure if there is a reason he did that. Maybe has something to do with the electric fuel pump or Mallory ignition? No idea.

Thanks for reading!
