Looking for a brake switch plug 79 C10
 

I have been having brake light problems for a while now, narrowed it down to the brake light switch plug. I have a 79 c10 frame off with a new painless harness. I believe I used the original plug for the brake light switch. it looks fine. Measured for continuity across the switch and it works. Measured 12 V for the power side of the plug and all good. connected plug, pushed brakes, no power to the other side of the plug. removed wires from the plug and connected straight to the switch. All is good. I have no idea.

Anybody know where I can get this plug?

Advanced, Autozone, local hotrod shop, classic parts of America and LMC, no good.

I can always just connect insulated connectors to the switch, but would like to have it correct.

Thoughts?

thanks
Chris

The connector for that switch is a Packard 56 custom Female plug. Shell # 2984235

Go yard surfing with your Packard terminal extractor...

If you have a bad connector, then check this site out.

Any body else out there? Not like you can see the plug and I can replace with insulated connectors, but would like to keep it original

Thanks

There should be a repair shop in your area that does electrical repair that would have Packard 56 terminals and the tool to crimp it or buy the tool and terminals and do it yourself. The whole setup doesn't cost much and you can fix any other electrical problem on the truck. just replace the terminals and slide back into the original plastic body.

it is the plastic body I am looking for. For some reason the brakes do not work when I have that plug hooked up. Right now I have the the plugs directly on the switch, I have the parts and the tool for the direct connect. I am just looking for a new housing

sorry-misunderstood. the plastic body shouldn't have any effect on powering the switch if the wires are all the way seated in the body and the body seats on to the switch completely.

Agree. everything works. But when i use the plug it does not. I don’t get it either.

The AC Delco PT142 is the connector shell and pigtail. Just buy one of them and extract the terminals.
Voila. The PT142 becomes a Delphi Packard 2984235...

The Brake lamp switch gets power from the fuse panel on one wire and the output wire runs to the Pak Con harmonica plug on the steering column.

The White brake light switch wire runs through the harmonica plug to the turnsignal switch and power from that wire gets routed to both rear turn wires by the switch. If the turn switch is dodgy it'll keep your brake lights from working.

Do both rear turnsignals work on Hazard and individually when LH & RH turn is selected with the ignition on?

Do you have juice on the Orange brake plug wire? This should have power regardless of ignition switch position.

I have checked all that. All works. Even replaced the turn signal switch because it was acting funny. Problem came back. Checked the switch it works. Checked the power wire on the plug and have 12 volts. Plug it on the switch and now power to the other side. Pull the terminals out and wire direct and they are still working after a week. I don’t get it

I redid the original plug. Adjusted the tabs a little. Working for now. Will keep tabs on it and change it to hard wire if needed
