Aftermarket tachometer

[freestylekyle310]

Hello, this is my first post here. I have a 74 f100 I put a 7.3 psd in. I used the factory instrument cluster out of the 74 and adapted it to the 97 wiring harness as much as I could. By doing that I do not have a tachometer anymore. I would like to put an aftermarket one in. Can anyone tell me if I can just use the wire that comes from the pcm to power the aftermarket tach? I would prefer to not use the auto meter alternator adapter if possible. I’m open to any other options as well.

I actually don't know about an aftermarket one. I am sure someone makes one, digital or otherwise that will work with it.

at one time I was going to put a PSD in a 86. I wanted to use the factory dash. I never got a chance to do it, but I was thinking, can I take the tach motor out of a PSD truck dash, and mount it in the factory spot of the 86 dash. Seemed like it would work, only problem is numbering would probably be off and not sure if that can be easily changed on the 86 platform.

That was also a thought but the 74 cluster never came with a spot for a tach so I would have to heavily modify it. I was also thinking I could take the the factory tach out of the psd cluster and modify it to fit in a standard aftermarket gauge pod. I don’t know if it will work but I have an extra cluster that I could experiment with.

Maybe a scan gauge or something like that hooked to the OBDII connector? Would get you tach as well as other channels if they were ever needed.

True, I’ve though about just getting a cts3 and calling it a day but that would be to easy right!? lol

Is it a 74 cluster or 84 cluster? Post #1 says an 84 cluster than post #3 says 74 cluster.

And, welcome to PSA! We would love to see some pictures of your 7.3 swaped ride.

It is a 74 cluster. Here is a few pictures, I’ll take some more this week
