look at the first picture with the highlighted part




You take the white wire that is no longer used ( Was pin S ) and you also take Tan/Blk Wire ( T ) and remove them both from the vehicle trans plug, pull the wires out of the loom about a foot and separate them from the main harness as they will now be used for your Input Speed Sensor ( ISS) You will need the proper plug and terminal ends to use on the wires to attach to your ISS. You will also need the appropriate crimper for those terminals.

At the PCM end, you will have to remove the loom and tape going to the PCM harness. The main harness divides into two and splits for each PCM connector. You remove the White Wire from the Blue connector ( Pin 79) and move it so that it can be run to the Green connector.

The Tan/Blk wire (pin 42) is already in the Green connector so all you have to do is remove it from Pin 42 and move it to its new location.

Myself I used the White wire as Pin A / Green Connector Pin 22
Tan/Blk wire as Pin B / Green Connector Pin 23

 

I have the ISS wired another way. I just added a connector the the front speed connector and ran 2 wires to the 22 and 23 of the ecu. I'm trying to figure out if I move the brown wire at the trans connector and move it to somewhere else at the pcm as well.

 

it also just threw a few codes, p0740, p0785, p1810

 

i think the segment swap wasn't done right, whatever that means lol. I wish I would have invested in hp tuners and not just done a mail order tune bc now I think I'll need to send it back to disable those codes, someone on ls1tech.com said the 4l80e doesn't use those codes

 

Mine has the P1810 too. Let me know what u find

 

from what i have read you just have to disable those codes because a 4l80e doesn't use them.
