Default Pics of good spot to tie into tach wire for tachout on 90-93

Like the title says. I found a yellow/blue stripe wire under the dash and tied into it. I couldn't tell which end was going to the tach so it looks like I tied into the wrong side because I have no tach signal with tachout enabled. After lying on my neck with my feet on the roll bar to get to this wire, I now feel like there has to be a better way. Anyone have any pics showing where they tied into the tach wire? I'm ready to give up on this tachout business and go back to the resistor in the diagnostics box.

I use the diagnostic box. Drilled a small hole in the back of the box, and put a wire into the proper connector. Easy, and because there's a rubber grommet right there in the firewall, routing is simple.

Sorry, cops with a diypnp. It was suggested that I quit messing with the factory tach signal and just used the diypnp tachout to drive the tach. I spliced in under the dash, but I think I hooked into the wrong half of the splice.
