This is a car used mostly for drag racing so Im currently going from a 4l60e to a th400 and I have the 4l60e removed. What do I do with the 4l60e wiring?
Is there any of it I need to keep or can I just delete it all?
I know there is a few wires at the shifter I will reuse for neutral safety and reverse lights but just wanting to make sure i dont remove anything that I might end up needing.
Thanks for the help

 

Keep the wiring Incase you want to go back or sell the car.

 

I deleted all mine and run my speedo off the front wheel;

 

Can you explain how that works? Will it work on an Lt1 4rth gen?

 

You connect the speedo wire to the front abs sensor and recalibrate the pcm until the mph is correct.Do a search on ls1tech and you should find a write up.

 

 

Thanks!
