Re: wiring harness replacement

Cannot help with a vendor suggestion as I have had no harnesses made but believe all are comparably priced and use similar quality components. Harnesses usually come in several segments depending on models and options. One vendor might advertise a cheaper price on one segment of a harness but if you are buying a complete multi segment replacement he will often make up for it on another portion.

When you get a vendor suggestion I would also ask the recommended vendor or the one you decide to use if they sell individual sockets and terminals separately as utility items and how quick is shipping if you should run across a need during the installation. Also ask if there are any connectors or sockets or portions of your old harness that are absolutely not replaceable and will need to be removed and reused. Some of the sockets, holders and terminals are obsolete and there is no choice but to reuse the old or use something modern but on others as I learned in a recent post, there are some obsolete items where a vendor has had them repro'd but availability is not well advertised.

47 uses Wade connectors to splice segments of harnesses together and while Wade terminals and single circuit inline connectors are available, the dual circuit in the same housing and the 4 wire single circuit connectors used both in the trunk and under the dash are hard to come by. Those you will probably need to reuse and if the terminals have never been out of the connectors before may be hard to remove. Take care not to break anything in the connectors when removing them from the old harness. If the car has factory turn signals, there are two resistors in the indicator light circuits that are mounted in what looks like two metal fuse holders that are covered by a cardboard tube. Those are positioned along the wiring under the dash. The specific size holders and the fuse like cartridge resistors may also not be readily found and may need to be reused.
