Lets play "Where can I get this wire"

[adamforsythe]

Ok bear with me.
What is the wire called that is on this distributor?
There is also a wire right next to that one what is that wire called (IT'S NOT IN THE PHOTO)? Where does it go to? The wire looks like this wire.

Do not know the correct name for that wire but it goes to the squarish box like thing at the top of the distributor. It plugs into the hei coil pack that sits on top of the distrib. And the other wire you are reffering to is that the other wire that plugs into the same place up there at the top of the distrib? If so it may be the tach wire.

I'll try my hand at it, The 3 wire plug in in your first picture is what I've always heard called the "module" plug.If you take your dist.cap off and look under the rotor button there should be a pick-up module there.If you look at the cap it's self, you'll see 5 connections in all 3 of the five are together (module plug) and the on left side front is the +12 from ignition, and the right side is tach lead.

Hope this helps,

yeah all besides those three wires in that plug are the 12v + and the tach wire,

thats is, total of 5 wires altogether on non ESC/EST systems

tach wire is not required

run a hot from a switched source like form fuse panel IGN port to +12v BATT on cap

all done



good luck

I look at your profile and see you have a 1985. The distributor you are asking about is for an old non-computor controlled truck. Your truck will have extra wires on the distributor and carb. for the computor.

not unless its a Cali truck. the plug bob is referring to is the ESC plug, which is wired to a knock sensor, when it senses spark knock, it retards the timing. if you pull the ESC distirbutor out, stab a non-ESC distributor in it, and plug in the 12v+ wire, it will fire up without issues. on Cali trucks got computer controlled carbs, everywhere else got a dual capacity accelerator pump. the dual capacity acclelerator pump is simply 12v wired through a temp sensor to the accelerator pump. it richens the mixture until the engine reaches operating temprature. it functions entirely independently of the ESC system.
