I got a wire harness for a lt1 with a T56 set up,and I have a 4l60e trans can I just add a wire to connect to the 4l60e?

You sure it's a 4L60E and not a 4L60/700R4.
I ask because a 4L60E takes a few more than one wire to make it work.
You would also need an automatic transmission engine computer. Or at least a memcal (chip).

How many pins are in the transmission connector?

Yea,it's a 4l60e has four pins I was going to buy a wire harness,but it's set for a t56 trans.I'm just going to get the right harness for it later.thxs for your reply.

Four pins in the electrical connector is a 700R4/4L60

The only thing electrical about that is the torque converter clutch solenoid.

Connector looks like this? (found in google search)
