Might try this for the temp guage>>> https://www.yotatech.com/f116/defini...ge-fix-271152/
This truck didnt come with the SR5 guage so I added it. If your truck is not Plug and Play like some are, you need to run a wire from the negative side of the coil to the little "p" to make the tach work.
Then what I did so as not to short out the electrical run beside it. I placed a piece of electrical tape over the little "p" and crimped a wire to the smallest connector that I could find.
Coming off of the negitive side of coil.
I then ran a wire to the negative side of the coil, on a carburator coil it is a little different then a standard coil you are most used to seeing. This is a temporary connection til I can come up with a better connection for it later on.
