I wanted to check with you guys about the wiring differences for a 6 vs 4 for the engine. I would think they are the same but want to check anyways. Also what about gauges? Will they work or do I have to go to autometers for all the importaint stuff? If this has been discussed I am sorry, I couldn't find anything on it.
You will need the gauges from the same year/model range as the motor! There are a few small wiring differences for the later motors but it is fairly simple. You will loose your gas gauge and you may need to run another wire from the oil temp or pressure sender depending on which wire you choose to run which gauge!
You can get an adaptor wiring harness from Jeff for the early motors but the 3.0L FI motor will require some pinout changes to make it work! If you go carbs it avoids some of the wiring issues!
Why loose the gas gauge. I don't think so.
The tab is different between a 4 and 6. But you can use the correct year 911 tach. Aux gauges may need additional wiring as they would for a four
You will certainly need to replace your 4 cylinder tach. If you stay with the 901 tranny, your current mechanical speedo is fine. Your fuel gauge will work assuming you are not messing with the fuel tank. Auxiliary gauges (temp, pressure, etc.) will require the correct sensors and appropriate wiring.
You can use this to keep the nice silver button/stock tach:

I will probably go autometer on all gauges plus tac. I want the tac to have a shift light anyways. And yes, my 2.7 already has webers, good ignition with box. It should run really well. The guy I got it from had some money into it.
