I'm trying to convert a 1971 firebird that has the basic clock/160mph speedo to a tach/speedo combo, the connection from the wiring harness is different than what I need for the tach combo. Does anyone know what the easiest way for me to do this conversion is?

Also if your looking for 70-73 parts, I have quite a few interior pieces in good condition email me with your needs.

sorry wrong generation for me can't help ya

 

Brad,
can you get the plug from the car your gauge pod came from? I did the same thing to my 81, but it already had a tach, I just upgraded to the 8K unit. You can trace the connections on the printed circuits, and move the wires in the plug accordingly. I am guessing that you will need a tach feed wire, though.

 

Thanks for the info Jon, is there somewhere I could get a wiring schematic for this, or is it gonna be a trial and error type thing?

service manual would be the best for schematic. I traced mine out, but it was a PITA. took a couple of hours.

 

thanks, I guess I'll be doing that over the next couple of days. Thats a lot of help, I was at the point of just ripping out all the wiring, and getting a painless wiring kit! (I'll probably end up doing that next year anyways)
