Where can I locate the Volvo Part Number on a wire harness?
There are a few locations where the part number can be located and it is different on some harnesses, however some original harnesses did not have one. All new or newer original Volvo harnesses will have a blue and white label (photo at right) on the black vinyl cover near one end (unless it has fallen off, which is common). On 700 series engine harnesses this label is nearest the gray 8-pin connectors near the right fender. Also on 700 series engine harnesses you will find the part number printed on a red vinyl tube (photo at right) located on one of the wires coming from a gray plastic 8-pin connector (usually near the left fender). 200 series harnesses will have the blue and white label near the ECU connector under the right side dash (for 83-84 and 85-87 240 non-turbos). The red tube with the part number will usually be located on the yellow or yellow/white wire going to the coolant temperature sender in the left side of the cylinder head under the intake manifold.
