wire colors
dumb question-
in my ignition harness on my 85 f-250 4x4 (the one that plugs into the distributor and oil/temp senders), i have two wires hanging in limbo, a red with a white stripe, and a red with yellow dots. I know one goes to the temp sender, but not sure which one, and I dont know what the other does..
also, this truck has a harness of wires that comes from over by the regulator, and wraps the whole way around the front of the truck and end up in a relay to the right of the brake booster. they dont go inside or anything. any one have a clue on that?? my 84 f150 doesnt have that. I was thinking maybe for a towing package or something??

R/W is temp (W/R is oil press). There are several circuits that use R/Y, so I don't know that one offhand. I suspect that other harness is trailer-related, but you'd have to get the Haynes and compare its wire colors to the diagrams.

this one doesn't have an electric fuel pump,but it has a feed&return line on the fuel pump. I don't remember exactly, cuz i ditched the ford holley for an edelbrock, i'll look on the carb.. it does look like it got pulled out of a connector of sorts. its a 351w

Looked in the haynes, red yellow is out of throttle kicker modual and runs carb vent solenoids, throttle position sol, decel throttle kicker sol, and is switched thru the oil pressure switch to the fuel pump relay, one would assume to keep it from running with no pressure. Me thinks it would have made more sense to cut spark than fuel....but I just drive them, not on the design team 
Give me some colors to look for and I'll see if I can figure out the other harness...but these diagrams leave something to be desired...
