Tach Adapter

What's up with having to buy a Tach Adapter for my Tachometer? Anyone else have this experience. The guy at the shop said due to the ignition system on the car they couldn't find a spot on the car (ignition coil, etc) to produce enough power to move the needle. At redline we could only get the needle on the aftermarket tach to hit 1000. I was under the impression it only needed to be hooked up to the wire running from the gauge cluster. Any help would be cool. Apparently any Tach Adapter will fix my problem but that shit doesn't seem like it's cheap.

does this have something to do with the Celica having a distributorless ignition?

I'm not so sure. Ask that guy about the adapter and how it works, if you can find out the essentials, I'm sure you can simulate the whole thing to get it to work. Maybe someone else that has a Aftermarket tach can help you. However, if it comes down to fabricating it yourself, i would lean toward the adapter. Do you know exactly how much it is? 15-20 Bucks doesn't seem so much to me, but if it's more then screw it.

Knowing the path and choosing the path are two different things.

yah, most retail for about $100. it just seems like bullshit that any aftermarket tach for the Celica won't work without this adapter cause i've never heard anyone mention this situation before

are you talking about the autometer 7 inch type tachs with the shift light? i have one of those and used the install guide on other celica website...worked fine for me, no need for a tach adapter

100DOLLARS! That's whack. There has to be a better way to get it working. I'm going to search the net for a little while to see what comes up.

MSD Ignition makes an adapter that works universally, and it's like 50 Bucks, which is better than 100 but still a lot. http://www.overboost.com/obs/product.asp?pid=2631 I wonder if you could use the wiring for the stock tachometer to hook up the new one, but then maybe the stock one wouldnt work anymore? I'm fresh out of ideas! grin

I don't want to call the guys at my shop stupid, but if the ignition system on the Toyota Celica was such that it prevented the use of aftermarket tachometers without an additional piece of equipment, I think I would have heard something about it on this site. The tachometer has power and I can get the needle to do the whole sweep in a testing mode so I don't understand why hooking it up the way the instructions suggest wouldn't work. I'll swing it by my dealership on Monday and see if they can help.
