Default 1972 Cutlass tic toc tac question

Hi, I am hoping someone might be able to answer my question here. I am restoring a 1972 cutlass coupe. I am restoring it as a 442 clone. This car that i have only had the idiot light gauge and clock (didn't work). I recently bought the two ralley gauges for my car. first gauge has the fuel, oil, and temp gauge instead of the idiot lights. second gauge is the tic toc tac. Now, my question is, do i have to purchase the ralley pac wiring harness that is advertised in the parts magazines i have such as Fusick, The Parts Place, or OPGI. If i don't need the wiring harness what parts will i need to buy. I was told by a local person, i would need to purchase sending units for the water, oil, etc. If that is the case, would you know what the part numbers would be and can a person get them at the parts store or are they hard to find. I would appreciate any help you can give me on this deal. thanks doug

No you dont have to purchase the wiring harness (for the dummy lights), I have the pin out for that you change from the idiot lights to the ralley pack. And you will need to purchase anew oil pressure sending unit and I think temp gauge (I forgot on this one). Check Year One website they will have the part numbers. As for the tach, I got the wiring from year one but from my understanding the tach will not work with aftermarket high energy ignitions. I talk to someone http://www.tachman.com/ that gave me that info and he can rebuild it to work with the higher output ignitions. There are alot of smart people here so someone with a lot more knowledge of this can confirm or debunk it. I hope this helps

Default gauges

You will need to reverse some of the wires in your existing wire harness. The sending gauges that you need can be purchased at just about any auto parts store, just make sure you buy the ones for gauges not lights. If you check this link it will help you with the wireing http://www.oldspower.com/vb/showthread.php?t=14827

The installation is pretty simple overall good luck to you.

Default rally gauges

Thanks for the input. The Tachman has my gauges right now restoring them. I will contact him and see if he can put some instructions in the box when he sends the gauges back. I understand I will have to purchase the oil sending unit and temp sending unit but just didn't know if they could be purchased locally or had to go to someone like Year One or other places. When i get the gauges back will be the real fun cause i am not a good wiring specialist nor claim to be. thanks again for the threads. doug

I don't see why it wouldn't. I am using the same tach with HEI as I had with the breaker points distributor. Maybe there's something about the Rallye Tach that I'm not aware of, but right off hand I can't think of anything that would be breaker-point specific.
