MPG Gauge - Electrical VSS
Id like to put in a fuel economy gauge that gives real time MPG results like the new trucks have, but I am running into some problems. I found the gauge, but It requires and electrical VSS. Is there someway of putting an electrical VSS on these trucks? I cant seem to find such a thing...
THanks!

A Vehicle Speed Sensor (VSS) should be available at most parts houses. I think they have to mount in a hole in the transmission or rear end to be positioned where they can output an electrical pulse each time a gear tooth passes by. Which, if any, would work for your application will likely take some serious research.

Here's a thread with some more info and a couple pictures. THe device is a bit crude, but is supposed to be very accurate.

Also, Piffery, would aftermarket products replace a OE hole, or would I have to drill a new hole in the transmission?

Thanks for the info. I find www.gassavers.org a intresting site. I see now what you have. As a possiblity you could put magnets on the drive shaft with a hall effect sensor or even a reed switch(old tech way) the only problem is calibrating it as you have to figure the rear end ratio/tire size. As a side note, I use a vacuum guage on my F250 4x4. I found that to be a good investment with helping on MPG. Higher vacuum while crusing gives better MPG.

Its easy, just mount it where you can see it, and run a vacuum hose to the manifold. The one I have I think came from JC whitney(pilfered out of a junkyard) has a lamp inside so you could use it at night. Its easy to use, once you get crusing, just let up on the throttle but stay crusing without dropping speed. I usually run about 12 to 15 inches of vacuum(at 60mph)I can also notice headwinds and weight of towing just by reading the gauge. On heavy headwind, vacuum is about 10 to 13 inches. Its a nice and easy way to get better MPG but its not going to tell you exactily the MPG.

What engine do you have? What transmissionm? What year is the truck? If it's an 85 with a 302 and an AOD trans you have one, the computer uses it to determine engine rpm and help trim the fuel mixture. If it's not a computer controlled beast AND you have cruise you have one, it's in line with the cable. It'll be a round connector with two wires somewhere between the trans and speedo, maybe even behind the dash. If you don't have cruise AND you don't have a computer then you DON'T have one.

Okay, take a look at the cable AT the transmisison. There should be a an electrical sensor there. It's bolted into the trans and the speedo cable hooks to it. Look behind the cable connection and you should find a connector.
