First poster here, I just installed a back-up cam in my Titan and I ran a relay from the reverse lights to activate the camera. The relay is mounted under the rear bumper - 3M plastic coated spade connectors plugged into the relay. Do I need to protect the connections with tape, dielectric grease, liquid tape, etc?

What are the risks of not protecting it, besides corrosion?

Thanks,

Steve

tuck it away somewhere inside the truck...no more worries. from what ive seen, there is no way to completely and permanantly stop moisture-exposed copper from corroding over time. it shouldn't be a really big deal to leave it there but why waste time later on messing with it if something goes wrong.

I usually tape around the contacts after I wire the relalys up.

Mikey's tricks:

#1 Cover the connection with dielectric grease before crimping and then heatshrink the package

#2 Get a crimper and solderless connectors made for aviation wiring. They generate many times the pressure that the automotive ones do. This coupled with #1 will ensure many years of service. I have a harness done this way under my airdam and it has held for over 10 years through salt & snow of winter
