71 f100 Firewall Wiring Connections/Destinations?

Post by 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
(image attached)

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.

You can use the 72' diagram to reliably wire that harness, (look at the distributor on the diagram and you'll find the wires location you need). :wink:

And I'd highly advise buying one of these as it's worth it's weight in gold when your broke down on the side of the road with a wiring issue! :thup:

Thanks Randy, the laminated one that I had was kept rolled up in the glove box and bailed me out more than once on the road! :D
