Your talking about the yellow wire with the red stripe? and what do you mean splice it?


Also I did end up reversing the black plug on the gas side and the white plug on the temp side. That is fixed Plugged everything in and RPM's are working blipped the throttle and it's working without splicing any wires.

Thank you for the help.
