So I screwed up the ignition wires

[tsubaki]

Just checking to see if you got all the wires hooked up or not.
The purple(s) could be a couple of things.
Is the tach working?
Is the overhead horn working?
Tach not working, it could be the wire for it.
Check the overhead horn by disconnecting it at the motor and with the key "on" (running isn't necessary) ground the wire from the harness to the powerhead.
