Few wires and switches questions

[84lngbed]

First is the pink wire that's goes toward the back of the truck on the main engine harness.


Second is a separate harness that was under the dash.



Plus the two switches.(one had a vacuum line going to it.)

1) What year is your truck?
2) Manual or auto transmission?

The first switch looks like a neutral / clutch safety switch for a manual transmission. Maybe brake light switch?

The second switch with the vacuum port looks like a cruise control disconnect.

Sorry. It's 1984 and a auto with a 700r4

The pink wire goes back to top of the gas tank and I think its for the fuel gauge. 2nd pic is door harness for power windows.

No I'm sorry. Your '84 is too new for me.

Here is a link to a wiring schematic that might help:

The first pic (single pic wire) is your fuel gauge sender. The 2nd is your main cruise control harness as evidenced by the 11/32 vacuum hose taped to the harness. On down it appears to show your stop light switch w/cruise option (hence the vacuum port). Hope this helps.

Forgot to label connectors when I took out the wiring harness and putting it back in now. Can anyone identify them.

Looks like headlight switch connector, factory radio power connector, dual tank selector connector and cruise control.
