A friend of mine changed his 1999 5.9 out for a 2002 engine and trans. When he did everything wired up except for the trans plug. The '99 had 3 wires on the plug. The '02 had 5. Does anyone know how to hook this up. He wired all 3 wires up and it ran but the odometer will not work and the overdrive light is on. Thanks for any help.
