Wiring on intake manifold & main battery ground

[Florian]

Hello,

I am about to finish wiring on my rebuilt engine. Now I came across these wires today:



Two of these wires are for the stock oil pressure and water temp gauges. I don´t need them anymore because I have got aftermarket units installed. The other wire (with the cable shoe) goes to the coil. I think I will still need this one, right?

It´s wire #16, I marked it here:




So I plan on removing the other two cables and the plug and connect the #16 directly. Do I also have to connect the fourth wire (#262) that enters the plug from inside the cab with the #16 wire?

Here is a link to a larger version of the wiring diagram: http://www.fordification.com/tech/wirin ... master.jpg



Now my second question: The main battery ground wire connects the engine to the firewall, right? It goes on a bolt in the firewall, but where is it bolted on the engine? I forgot to take a picture of this during removal and can´t find a good place to hook it up to. Maybe the new intake and heads haven´t got the provision for that like the stock ones had? Where should I attach this wire on the engine?




Thanks!

Florian

16 is the resistor wire for the points in the dist. it shouldnt be removed at all. if point or soem elecetronic ignition systems are being used. with 16 is also a start up only brown wire from the starter relay. here is a diagram for wiring in some electronic ignition systems. http://www.fordification.com/forum/view ... =8&t=48178 i would check before cutting any of those wires.

the ground strap botls to the intake manifold under the throttle linkage originally. if there is no botl holes there because of a different intake now. then it can be botled to any botl up there on the engine you can reach it with. or witha heavy enough gauge of wire. it can be made longer and a different wire used to bolt to the nearest bolt.

Thanks for the reply fordman!

I can bolt the ground wire to the bolt holes of the throttle linkage, just forgot that it went there.


I think you misunderstood me, I don´t want to remove wire #16, I only want to remove wires #31 and #39 because I don´t need the stock gauges in the instrument cluster anymore. So after removing these two wires there is only #16 left on the male side of the plug connection. But on the female side there are four wires entering the plug, there´s one more wire which is #262. I wanted to know if I still need that one after I removed #31 and 39. I want to leave out the plug connector and connect #16 directly with a luster terminal.

Ah, and I´m using a stock distributor with Pertronix Ignitor

wire 262 is the brown wire that comes from the starter relay. and only has power when you start the truck. it just gives a full 12 volts at engine start or engine cranking only. after the ignition switch is let go of. the wire becomes a dead wire. there is possibly no reason to remove it. i am not sure i would remove the wires from inside the cab. as long as the other wires on the manifold aren't hooked up there will be no readings being sent through those wires. capping the wires off on the manifold would be good enough. if you ever need to reuse them for some reason. i wouldn't remove wire 262 at all.

Okay, I think you´re right, capping them on the intake side of the plug only is probably the best and easiest thing to do! Thanks fordman!
