I think its time to give in and buy a new wiring harness

I just wouldnt take a loom out of a car. did it once and regretted every minute after.
unless something has shorted out and melted huge chunks of it, the issues are with the last 6 inches of wire and the connectors.
the areas exposed to oil, heat, damp, their own weight, or road salt get brittle and tired.

if you have ever unwrapped a large portion of a 50+ year old chrylser loom you will find perfectly good cable 2 inches back from the end of the wrap, in a rainbow of vibrant colours, like it was put there yesturday.


crimp tool, non adhesive cling style wire wrap, heat shrink, soldering iron and an ability to do a linemans splice

having an ebay tool set for removing connectors from plastic modular plugs is handy or just make your own from ground down hacksaw blade and a bit of dowel.

find problem wire, cut back to bright copper, splice in new wire, solder and cover in heat shrink put on boot or crimp on new connector and put connector in plastic plug. when a section is done cling wrap again start with 3 rounds angle and carry on. end with 3 ot 4 rounds or slip over large heat shrink and shrink it on as a pistive physical end to the wrap.

Next

then clean the fuse box and fuses
bulkhead connector
re do earth staps and the power leads to the starter solenoid with new spiky washers
if using non standard battery clamps that bolt on to the cables get new solder on ones or unbolt them from the cable ends and clean up the green gunge you find. battery fumes migrate up into the clamp to wire junction and corrode it.

car will run better than it ever has

remove stupid addons as you find em, and re insulate with cling tape, don't be afraid to cut a wire and slide on heat shrink to fix bad scotchlock chewing.

the worst you will find is the odd "friday afternoon" job hidden in the depths of the loom a red wire in at one end a red wire out at the other, but a short lenght of something else hidden in the middle under the wrap where they thought you'd never see.... "last loom of the shift can't be botherd to get a new spool of red from the stores".... spliced in with solder just like your repairs

this is an area of old car hobby where lots of time and money is wasted replacing 100% when only 10% was at fault.

wireing in big fans and electric pump...
new fuse box
relay to stwich it on off the key switch
power from battery
do the ammeter bypass
master fuse or breaker
new wires for all your new stuff
