71 f100 Firewall Wiring Connections/Destinations?

[71EVOLUTION]

Good Evening All:

I acquired a 71 f100 shortbed 4x4 that was completely dismantled as the previous owner was going to paint the inside and out, but lost interest & parts sat in buckets for years. I've assembled a majority of the truck, but I am left with several wiring connections that I don't know where they go to.

1. Ther is a grommet from the driver side firewall to the engine bay that has 4 wires that coalesce into a single female quick attach grommet. I believe that one wire goes to the coil, another to the oil temperature sending unit and it appears that the other two bceome one as there are only 3 wire connections on the other 'outlet' side of that quic-connect. I am missing that male connection that attaches to it leading to the engine etc & I cannot find one anywhere to purchase. Can anyone identify where these wires go?
-There is a large "pink" wire that goes alongside a brown wire that appears to feed into the same socket
-There is a Yellow Wire with thin Red Stripe
-There is a Red Wire with a thin White Stripe

For the life of me I cannot find a photo or an image as to where these wires go; and I'd really like to locate & buy a connection with the wires to the engine etc if anyone knows of?

Any help would be Greatly Appreciated.

Here are the wiring diagrams from Fordification, there isn't a 1971 wiring diagram, but I believe the 1972 is the closest to your truck. Go down the page to the 1972 F-series quick reference diagram and you see a brown wire and a pink wire that turns into a red wire with a green stripe, it goes to the coil. There is a red wire with a white stripe that goes to the temp sending unit, and a white wire with a red stripe that goes to the oil pressure switch.

There is also a Ford truck wire color and gauge chart a little below that. I have read in the past that some members have used Mustang Unlimited to get a similar wire replacement to use on our trucks. Hope this helps.

Thank You 390FE1072; I appreciate your reply & will try to I.D. these w the diagram reference.

I was able to look at an acquaintances 72 f100 4x4 yesterday and that same factory wiring harness in question on that pickup oddly enough- had different colored wires running into the quick connect from the firewall it (and in different locations on the factory quick connect) - crazy.

Hoping someone might be able to take a similar pic of their quick connect and if it's the same as mine, possibly ID where each wire runs from it to the engine bay and where I should connect these too.

Appreciate it!

Ford used the same "Dash to Engine Gauge Feed Harness" configuration across virtually all car/truck/van models from the late 50's thru the early 70's, a pigtail with 3 wires, 1 female connection and 2 male connections. I bought one for a Mustang and used it in my '64 Fairlane. They were in Mustangs, Torinos, Fairlanes, trucks, vans, anything with a coil, temp sender and oil pressure sender. The basic part number was 14289 and you'll find them with many prefixes and suffixes like B7C-14289-A and C8TZ-14289-E https://cgfordparts.com/wwwsectionfiles ... ed-Harness. There were scores of different prefixes/suffixes depending on the model and wire colors may have been different but all had the same basic configuration, a 3 wire pigtail with a male bullet and 2 female bullet connections. For your truck the part number was most likely D1TZ-14289-B. https://cgfordparts.com/ufolder/fordpar ... 1TZ-14289B will work.

In the photo below I have shown the 1969 wiring connections on the left http://www.fordification.com/tech/wirin ... rging2.jpg and the 1972 wiring connections on the right http://www.fordification.com/tech/wirin ... _quick.jpg. Both diagrams show how the pink resistor wire (#16A) splices in with the brown wire from the starter solenoid (#262) to go to the red/green wire to the coil (#16). The brown wire provides a full 12v for starting and the pink wire provides the reduced 9v to the points for running. The other 2 wires go to the oil pressure sender (center plug connection, white with red stripe, wire #31) and temperature sender (end plug connection, red with white stripe, wire #39). Your yellow/red wire was probably white but yellowed with age. I'm not 100% certain but the '69 diagram shows the male pin on the pigtail went to the water temp sender. The wire from the pigtail that is directly related to the 2 wires joined on the firewall side of the plug will go to the coil.

Wow!
I cannot Thank you enough SargentRS; that is exactly what I needed and I've been mudding thru trying to identify that for quite a while.
Much Appreciated!
