1981 F150 fuse box connections

What is the C1960, C1961, and C1962 used for in 1981 F150 fuse box and where do I get connectors for those locations if those are for adding extra circuits.

Frank - That's a good question. I believe they are four of the power feeds to the fuse box, as shown below from the 1981 EVTM. But which they are I don't know. I can't get to the shop now to check out a fuse box, but maybe someone else can?

But I don't think they are for adding circuits.

Apologies if I am missing something but with 1960 and 1962 being the power windows/locks it would just require [carefully] taking those connections out of another truck and inserting them into your fuse block. Just did this the other day.

1961 is a new one to me but I am interested in why it says aux battery AND clock/4wd indicator.

I just have the 1980 EVTM handy at the moment and while it's different (the power windows only being for the bronco rear) it also has the W/P wire from the block going to the Accessory Safety Relay (aux battery relay). The diagram for the aux battery shows power going to the 4wd indicator, clock, and speed control amplifier.
I don't want to get too far off your question Frank but did those things really get their power from the aux battery (if present)?

Visiting the online 1986 EVTM I see that 1961 is then just for the 4wd indicator. I noticed when installing the power window/lock connectors that there was another similar plug in connector on the back but didn't trace the wire.

So it would seem that one could easily pull those connectors from other trucks and have factory fused live power.

The easiest way, as was mentioned, is to find a truck with the needed equipment. I will warn you, the power window and door locks harness runs across the firewall inside, just below the windshield. Removing the top pad of the dash will allow access to this area.

When I initially added those items to Darth, I pulled the harness and one door from a 1990 F250 XLT Lariat and the connectors plugged right in to the 1986 fuse box. Based on this, I would expect you can use any 1980-1991 for those features. If you are just looking for the taps, just look in junkyards for the connectors.

What I have found is some of the taps that are for a particular option that has a dedicated feed (nothing else on the fuse or circuit breaker) the tap is usually inserted from the rear and actually becomes the protected end connector for the fuse or circuit breaker.

Motorcraft may still list some of these in their pigtail catalog in the single connection portion.

Scott - I don't have the 1980 EVTM, but here's a page from the 1981 version. Is this what yours shows? This one shows that the same circuit that pulls the relay in also powers the digital clock and 4wd indicator. But that's just pulling the relay in to parallel the batteries - they aren't powered by the aux battery.

Gary, you are absolutely right. I was reading this entirely wrong. It had never dawned on me that if you don't have those options but want to add some other accessory that you could use one of those snap in connectors and have factory looking fused wiring (assuming load is acceptable) so I'll blame it on being excited by that revelation thanks to Frank

.

The 1980 doesn't have the illustration like that but still shows the same thing in the diagram.

I think we need to document this with some pics and examples. I’ve not looked at those connectors closely enough to know what is possible.

Agreed! I see that there is a carb circuit also that uses a connector. May be another point where an accessory could be added in if unused.I am going to see about that in the jy later this week and can take some photos if no one else has any handy and posts them before then.

Thanks everyone, I need to go to a pick and pull and see what I can find. There's one about 50 miles from me. I am just wanting to add a few fused circuits and be able to go directly to the fuse box without using those fuse taps as my fuse box lid would no longer fit, plus it would be a seamless addition. My future plans are for a pair of auxiliary reverse lights, some additional marker lights, and some lights to illuminate to the side that will come on when my turn signal is on. Some things will tie in to the existing circuits and some will be their own dedicated circuits, depending on the additional amperage load. Pictures of the connectors that are inserted into the fuse box would be handy. Perhaps those connectors would be available new as well making wiring additional circuits to the fuse box a cinch. Also Gary, documenting any information uncovered on this would surely be helpfull to others.
