So I baught a autometer boost vac gauge and when i was pulling the wiring harness through the firewall and the plug that plugs into the back of the gauge did not make it through the hole with the wires. so now i have a hand full of wires and a plug and i don't want to guess where they go back into the plug. If someone could check there gauge and tell me what wires go where in relationship with the plug that would save my night, because autometer tech support is closed.
