[forPETEsake]

I've been struggling on this for a week already. I'm the type to do my research and I finally decided to make am account and ask for help here.

I have a 73 240z with and lt1 6 speed from a ws6. Can anybody point me to the right direction on how to wire it please. Thank you.

lt1swap.com

 

A goldmine of information is available on that site--to include step-by-step guides with pics.  I was able to take a stock truck harness and build a standalone using only the information on that site, on  my first try with no previous experience with computer controlled systems.  The owner of the site also flashed my PCM for a good price and took less than a week.  

 

Edit:  the website was missing the "1".  should read lt1swap.com.  Apologies.

Its really not that bad if you break it down into manageable sections and not try to take it all in at once. I think I used the site ukcats suggested, it is a good write up. I even made my own VATS box and the car fired right up once I had power and fuel.

My bad you have a LT, you might get a little more guidance in the I and II forum. Nonetheless the process should be similar, get the Z wiring diagram (available somewhere on this site) and track down the needed inputs from the car harness to the GM ecm. Break it down to individual circuits, start, accessory, ground etc and it'll be easier than you expect.
