How do you clean the 7 pin wire harness connector plug

[Goldie50]

On my way from the Dallas area to Angel Fire NM a warning light on my Ford F-150 indicated the turn and brake signals were not working. I pulled over and unplugged and plugged back in the connector plug and the lights started working. What is the best way to clean the contacts in the wiring harness?

I have a spray can of electronic cleaner. Works great.

Sometimes I apply a little dielectric grease to the contacts.

If I see any corrosion or very dark copper on either end I clean with very fine sandpaper. I take a tiny twist of it and swirl it in each socket. Then blow out the dust. Same of the posts of the other end with a strip that I rub around each post.


Don't over do it as some have a copper coating over steel.



Dialectric grease to keep it clean and shiny.

I used to use dielectric grease on contacts. I no longer do because of the problem of it attracting dirt.

Soak the pins with contact cleaner, let dry, and reconnect.

I sprayed contacts with WD40 and it worked for a while but ultimately had to have the plug socket on my Silverado replaced. No further problems. Was told that one or more of the contacts had gotten corroded. Think the fix at a dealer including part and labor was $100. I stopped on the way out of town on a 1000 mile trip and knew I could not risk the drive without working brakes. One of the benefits of living in a small town. In and out in less than 1 hour.

I only use CRC Electronic cleaner in the spray can. Works great on the plug and socket.

Found in most hardware stores or at Amazon.
