Replacing wire harness's

[Big Mo]

Asking your suggestions if I need to replace all the wire harness's. Other than a couple splices made over the years I had no problems. If I need to replace them who is a good supplier to buy from?

As long as the insulation is still flexible and your splices are good, I see no need to replace. You can rewrap any bad spots in the tape by using NON-adhesive black tape. I use this http://www.ebay.com/itm/2-Rolls-Factory-Electrical-Non-Adheasive-Wiring-Harness-Friction-Tape-OEM-M-/200913703021?pt=Vintage_Car_Truck_Parts_Accessories&hash=item2ec763d06d&vxp=mtr

Some De-Ox Red or similar contact cleaner on the plugs if you need to clean them up.
