Tachometer connection?

My truck didn't come with a stock tach - is this where the green wire would go?

yup i just did mine a few days ago. i used a male connector to plug into that. hot wire in the ignition fuse. backlight wire in the taillight fuse. (taillight fuse is your running/parking lights).

You can hook up the the tack to the + and - battery then plug it into that to test before you mount it and all. you can even test the backlight by just touching it to the battery

If your tach does not work, you will need to run a wire from the negative side of the coil to the "p" on the back of the cluster.

Copied.
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 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.

I used tape for insulation and to make my connection to the "p".


This is a temporary connection and is on a 22r Motor.

make sure you dont leave any part of that service tach plug/ignitor negative connection exposed like that above pic. seal it up good with elec tape. the fsm says if that wire gets grounded it could ruin your electrical system
