Black Connector
5- Ignition Control
14-Distributor Ignition Feed
23-EVAP switch feed.

None of these are used.

Blue Connector
3- PCM Ignition Feed
10- EVAP Canister Purge
15-Skip Shift Lamp Control
20-Output Service Enable
24-Evaporator temp signal
30- Serial Data

Blue 3 could have been used in Blue 19 but you used the other ignition there. So it can be deleted, remember there is 12v there so delete it properly. Provided you do not want the skip shift all of these can be deleted.

Clear
11- Traction control active signal.

This will be deleted.

Red
9- EGR Vacuum Signal
12-BCM TPS Signal
14-AIR Pump Relay Control
23-Traction Control Spark Retard

These get deleted also, these LTX emissions are not compatible with the lsx pcm.

Good Luck

are you using the eficonnection diy kit? Did your cam sensor connector come on a harness with a 4 cavity connector that connects on the passenger side of the intake?

Yes I am using theyre diy 96-97 kit for my 96 harness and here's a pic of it the bag says gen iv ls cam position sensor has the red,pink and brown wires just like u said green.



I just am confused as to what I should do with the black 2 and 20 I have pinned in the ls1 blue 73 and 61 if the cam position sensor pins belong there.

Again thanks guys this is my first time repinning any wiring and everything went smooth and has been going smoot just hit one small snag.
