Electrical wiring

[JMBT]

On the exposed connections, like battery terminals, starter terminals, chassis grounds,..etc I have found if you clean them good then spray them with cheap spray paint it works just as good as the expensive stuff. Do several coats.

Also while you are working on electrics, take all your connections apart, sensors, ECM connections, anything you can take apart, disconnect them, spray them thoroughly with contact cleaner then grease them with dielectric grease.

You can also go through both fuse boxes, especially the one outside in the engine bay, pull each fuse and relay, clean their prongs with emery cloth and apply a THIN coat of dielectric grease, then cleaner the contacts they plug into in the fuse box and plug them back in. It takes awhile to do all this but it will save you headaches down the road.

As always disconnect batteries before doing this kind of service.
