Where do you connect the tach on DIS?

[1st Ranger]

I have a 1990 Ranger with a 2.3L DIS. The Chilton's manual I have for it shows the wiring diagram for the V6 but not for the 4 banger, what wire do I hook the tach to?

its supposed to go on any of the coil packs wires, but not sure, u better wait for some more input.
welcome to TRS by the way

do the instructions for your tach say which wire to hook it too? heres a link from the tech library if you havent read it already.

Thanks for the link.

The tach instructions do not say but after looking at the link you sent me it looks like it goes to pin 4 on the PCM which is the same connection point as the V6. I'll have to try it out next weekend and see how it works.

I got it to work. The Haynes manual has a good diagram of the DIS system. It does connect to pin 4 of the PCM, it is a green wire with a yellow strip.
