Hello i have a 87 tbird 5.0 digtal guage cluster will that work?

Or you can mod your tach. I soldered a 100k resistor in parallel with the one that's already there. Works like a charm. Thanks Eric (CoolCats)

I'm guessing what you are looking for is somewhat rare ... would probably need to get a KMH cluster and then find a separate V8 tach/cluster and swap the tach over.  It's not that hard once you have both out of their respective cars.

I had to do something similar.  Obtained a 140mph cluster out of a Turbo Coupe and then swapped a V8 tach into it.

I read about that mod a long time ago and I actually have everything to do that, was planning to tackle that mod this week but I have heard some people having issues with that mod. Sluggish response, struggles to keep up after 4k rpm, and some say is not very accurate. What is your experience with it?

Thanks John! I read about that mod a long time ago and I actually have everything to do that, was planning to tackle that mod this week but I have heard some people having issues with that mod.

I have an buttstuffog cluster out of a sport that I'll sell for $75.  It gets you part of the way at least - the tachometer.

And some have no clue, with the mod you have a tach that's identical to Sport but has a TC face... It may not be perfectly accurate but rarely are the Sport units...

There's this option as well as far as the speedo goes, but you'd have to reach out to them to see if they can offer anything in the KMH realm and they don't offer a V8 tach ... at least not yet:

Hey Jeff
My choice to do the mod was so I could keep the factory boost gauge for my 5.0T project. I can understand why some would say it seems sluggish. I thought that also since I had been driving with the tach pegging in 4cyl mode for years. As for its accuracy..... Mine is only a couple hundred rpm off on the slow side. It's livable since most fox mustangs I've played with are about 500 rpm slow. If your concerned about accurate rpm for shifting......do what I did.....install a shift buzzer http://www.modifry.com/index.php?route=product/product&path=18_66&product_id=66 this thing is awesome.

If you shoot me your email I can send you a short video of the tach in action compared to what the ECU sees. I'd post here but it appears I can only link to a video. Don't care to set up photobucket.
