wireing abnormalities!
A couple of days ago my truck started missing at idle after warming up and the "choke" shutting off. so i did like any sane person and open the hook and look for anything thats looks off. while checking the sensors for bad connection and wire harness for any chaffing, i looked at the coil and its plugs. i immediately noticed something wasnt right as there was a wire that had been tapped into the red wire on the plug that goes to the coil. this could be easily explained if there was an aftermarket tach or something of that sort, but there isnt any. so i trace this wire out. which by the way is a 16gauge speaker wire that had both leads soldered together and tapped in, then had a 20a bus fuze spliced into that and the wire ended up at the plug for the high pressure fuel pump. so i thought ok .. some one is a moron, but it gets better. not only is it tapped into the fuel pump. but the fuel pump is still getting its power from the relay -N- inertia switch as the way ford designed. its really a what the (fill in blank here) kind of things. so i was just curious if any one else has run into those WT(fill in blank) kind of things on your rides that a previous genious decided to add.

Lol wow that is an interesting one.
Let's see. My personal favorite. My dad bought an '85 Silveardo regular cab, which he stripped completely down and put a 454 in.
He pops the hood for the first time and his jaw about hits the ground. The guy who had it before him had replaced every single wire....with red. Red was EVERYWHERE. ANYTHING and EVERYTHING that required a wire...was red.
There was one back cable on the truck, and that was the battery negative. Thank God for carbed engines, or he woulda been in for a nightmare of even worse proportions.
On mine: The water temperature gauge wire and oil pressure gauge wire both had wires spliced into them that went nowhere. They were spliced in then they were spliced in again. I guess for some sort of electrical aftermarket gauges.
But my favorite on my truck. When installing my fog lights I noticed a worn out white wire sitting on the bumper under the truck. So naturally, curious me follows it. It takes a winding path of twists and turns, I track it through the engine bay, into the truck, through a grommet in the floor, back through another into the cab, back out through another, under the truck to the rear bumper, where it ends. Nothing at either end. Still wonder what that was...

didnt you know that white wire has a high importance. it was put there for the static discharge. being that you have a 12v. system source but yet with the coil pack build up to 100kv you have to drain the excess energy out or.. or your hair will stand up as you drive. heh this info comes straight from the I.M. bsingu file.txt which was found first on the datson pickup in tokyo, japan. lol

Reall I absolutely MUST get that text file to save, it seems of utmost importance!
And I'll DEFINETLY have to put that wire back in. Heck I might even up it to 00 gauge and run another one cross-ways for good measure. Never can have too much, right?

I have probably given a few people those WTF moments more than once. I have a tendancy to modify things (gee what a shock) and I will ue whatever I decide works best so that means the next person to go try and replace someting may or may not have a clue what it cam from. example I have used GM alt on a lot of vehicles. Other things are swaping motors in, then selling the vehicle, just ran into this actually there was a guy insisting at the local napa store that they were giving him the wrong valve cover gaskets because they didn't fit. Well he told them that he had a 400 and these gaskets are for something else, so they were looking them up when I happened to glance over and noticed that there were infact 400 VC gaskets. i finally got him to go out and bring in one of the valve covers (he had them in his other vehicle to bring down for comparison but didn't bring them in DOH) Someone had swapped in a 460 and he didn't know it.

I doubt it he had bought the truck to basically restore thinking it was all original 78 F150, then finds out it's got a transplanted 460 in it, means that it's not original (but also tells me someone did a nice job if he didn't even notice it was transplanted). he basically now wants to find and rebuild a 351m/400 to put in place so more money as the 460 appearently runs real good, he thought he had a good start.
