280z4me2 Posted September 27, 2012 Share Posted September 27, 2012 Swapping an LT1 into my 76 280z. Car had electrical issues so all harnesses were trashed. I have plans to do a painless kit for all interior controls and the motor on a stand alone harness. I was looking at buying all autometer mechanical gauges but I do like the looks of the stock gauges and it would be much cheaper to keep them. What would be the easiest route to take with wiring in stock gauges? Should I buy all 240z gauges since they are mechanical since I am not using that portion of the motors wiring harness and sensors? Also, the T56 clutch master cylinder . What would you recommend as a bolt in unit? Anyone running stock? Quote Link to comment Share on other sites More sharing options...
GOTHALOSISM Posted September 28, 2012 Share Posted September 28, 2012 If you want to use the stock speedo your going to have to get a converter box from the tranny. The tranny has an electric signal to the gauges, and the stocks are mechanical. The tach you run off of the standalone harness with a resistor to get it to function right. The water temp / oil pressure gauges are run off of the stock sending units from the L6. For the oil just get a t-fitting and toss the sending unit on there. The water temp is the same in the side of the block between 2,4 cylinders. As far as the clutch master I went with a willwood 7/8'ths, I'm not running the t56 though.
