Mystery Module
Greetings....I have a restored 78 F-150 302, C4.
Does anyone have any information about the electronic module located behind the dash panel on driver's side. It seem to be connected to the ignition coil and the vacuum modulator valve on the left valve cover and controls the anti dieseling solenoid I believe. Need some data and/or schematic or source thereof. Any help or comments would be appreciated.....

Are you talking about under the hood in front of the firewall or
it is actually under the dashboard inside the truck??
What colour is it and where is it mounted ?
I've checked my book and see nothing like you're describing.

Dennis......Its located just behind the left side of the dash panel. A black plastic case about 3 x 5 x 2 in. Having an electronic background, my educated guess is that the module samples pulses from the ign. coil and uses them to modulate the vacuum solenoid mounted on the left valve cover which in turn modulates the vacuum diaphram on the anti-dieseling solenoid. I think it acts as and electronic dash pot to prevent engine stalling when releasing the accelerator quickly (auto-trans). The control valve on the carb. seems to be a combo dash-pot/anti-dieseling solenoid.....I have not been able to find any mention of this module in any book or manual etc.

That's tied to the ignition.
I have a photo of one.

Hey Dennis!
My seat belt buzzer box is red on both my trucks.
I believe this guy has found some sort of secret tracking device. I think the government is watching him. We should be careful, we could be dragged into this conspiracy!
Honestly, I've spent some time under the dash and I have no idea what this guy has dug up but, his explanation is a hum dinger!
Good Luck, Have Fun,

My empire for a photo of this object !!!!

You may be right. A lot of black helicopters have been flying around the house lately. It's just my luck to have a "one-of" truck. When I had this truck apart for resto, I traced the harness out and it does drive the vacuum solenoid on the left valve cover. It is apparent the module was from the factory. This truck was a basket case when I got it. Everything on it was worn out but the sheet metal was good so it became a winter project. Fixed and solved all problems except this one. Nobody has ever heard of this mystery module and I must have the only truck in the universe with it. If I had a scanner I could show you what it looks like. Oh well.....thanks anyway.

Vacuum Huh ?
What is the calibration code for that truck.
It should be on a white sticker stuck to one of the valve covers.
I'll see if it shows up in the vacuum diagrams.
I just need the calibration code to know where to look.
