Replacement wire harness plugs and connectors

Rembrant
Is anybody making replacement plugs and connectors that match the OEM plugs on my truck?

What are you guys doing when/if you need to repair or replace a plug/connector in the engine bay or elsewhere on the truck?. I have one now with a broken spade in it, but the rest of them are old and brittle anyway.

I have a stash of wiring harnii from which I pull the needed connector.  But some of them are still available. See the catalogs on: Electrical/Wiring Connectors.

Ditto on many salvaged in excellent condition pieces. I also have the spade connectors for the non-molded male/female connectors. I can get those numbers and pictures if needed.

Many of the round pin male and female are used both inside the cab and on the chassis and the interior ones are usually in much better condition and were used on other vehicles than trucks. Ford continued using some of these into the mid to late 90s and possibly longer. If the wire insulation has started to disintegrate, the pigtails will probably be your best bet and the splice kits Ford provides with the kits are terrific and weatherproof once the sleeve is heated to seal the repair.

The one's I'm referring to are the old round connectors with the flat spade terminals. I don't see them in that catalog...unless I missed them. I guess I could update them to a more modern connector...I'll check with the dealer next time I'm driving by.

Ok, you are referring to the molded ones like the Duraspark system uses. In the Motorcraft connector catalog, quick look, WPT-350 is a female 3 cavity connector like the DS-II uses, WPT-601 looks exactly like I remember mine using.

Yes, the round moulded connectors. They're used for everything on my truck from the reverse switch on the trans to the voltage reg to the DSII module. I'll post a picture tonight, but I think it is the plug on the voltage reg that has a spade broken off inside.

Back to working on wiring again...

What is this little thing? Condenser? The plug broke off with ease. Do I need to replace, or can I bin it?



It was originally mounted under the lower screw holding my voltage regulator to the fender, see old picture below.

Check your radio before placing it in the bin.  That's a capacitor/condenser that removed electrical noise from the electrical system.  Oddly enough, only the V8 powered vehicles got them, but they filtered out noise that showed up in the radio as a background buzz, particularly on AM signals.  If you don't have any noise in the radio then toss it.

I just checked it...no noise...none whatsoever!...lol.



Thanks Gary. I'm going to bin it.

Ok, I have another electrical question coming shortly...just need to grab a picture...

Below is a picture of the plug that I started the thread about in the first place. One of the spades came out with the other end of the connector. Corroded and broken. I'm just going to chop the bugger off and bypass it. This is the plug that sits right below the voltage reg and starter solenoid. Future plans are to remove all of this stuff. I know a 3G alternator will get rid of the voltage reg on the fender correct? What about the starter solenoid...is there a starter swap that deletes the external solenoid as well?



Back a little further on the passenger fender just in front of the heater box, I was cleaning up the harness and removing loose electrical tape, and found some old repairs that were held together with said tape. Is there something missing here...or any idea why this was done? (A well known problem perhaps?). I guess I'll go digging in my manuals and see if I have a wiring diagram of this harness.

Yes, a 3G swap does away with the external voltage regulator on the fender.

But a starter swap to a PMGR starter doesn't really do away with the need for some kind of a relay.  However, you certainly don't need something the size of the starter relay/solenoid you now have.  Bill says the heavy duty Bosch style relays are enough to bring the starter-mounted relay in, and I'm going to go with way with my trucks.  But, I haven't done so yet so don't have anything to show you.  However, do you really need to get rid of yours?

As for that wiring, what was missing when it was done was intelligence.  The red/black wire has a feed and fuse holder for some new accessory, like a radio.  Presumably the green/black wire had a tap on it as well.

Ok, here's the scoop. I know what was done, but I'm still not 100% sure why...

There is a 250v/7a fuse in that holder, and the wire is a jumper between red/black wire that goes to the headlight, and a black/red wire that goes to the blower motor. The green/black wire that is also stripped goes to the headlight as well.

I wonder if this was a homegrown method of creating daytime running lights? My truck has the low beam lights on all the time when the truck is running, even when the light switch is off. Presumably, they tapped into the green/black wire first only to find out it was the high beam, and then switched to the red/black which is the low beam?

The black/red wire going to the blower motor, is it 12v+ all the time?

From what I remember blower 12V feed is hot in run and accessory. It would work, but... Damn if I would have done it that way. The factory DRL system is kind of weird in it's own way.

Yeah, I wouldn't have done it that way either. Anyhow, I'm going to remove the jumper and clean up the wiring. I guess I'll find out later if its OK when the truck is back up and running.

Thanks for the help guys.
