Can't find this anywhere. Already searched.
Are these connectors compatible? Can you go from one to the other?





4L60e park neutral connector swap

They seem to have the same "signals" but for 2 wires that might be the same, but with a different names. They even have the same amount of wires and even most same colors.

I'm swapping a V8 (LS type) into a 2006 Trailblazer, keeping the original trans. The original trans has the 1 connector switch, while the engine harness has the 2 connectors harness (2003 LQ9)

Any help/guide/suggestion is highly appreciated.

2: Not Used.
3: Not Used.
4: Trans Range Switch Sig B. *** D/C1 Trans Range Switch Sig B.
5: Trans Range Switch Sig A. *** A/C1 Trans Range Switch Sig A.
6: Trans Range Switch Sig C. *** B/C1 Trans Range Switch Sig C.
7: GND. *** D/C2 GND.
8: Trans Range Switch Sig P. *** C/C1 Trans Range Switch Sig P.
9: Park Neutral Position Switch Sig. *** B/C2 Park Neutral Position Park Switch Sig.
10: Back Up Lamp *** F/C2 Back Up Lamp
11: Ignition 1 Voltage *** C/C2 Ignition 1 Voltage.
12: Ignition 1 Voltage *** What goes in here? I have: Neutral Safety Switch Park/Neutral signal not assigned on G/C2, but I'm not sure.

I know this post is old...but did you find the answer? I have the same question

Yes, either one will work. The newer one has a better plug, the older ones are glued in and hard to get out.

There's so much info for the older style plug, some reason newer one is mystical lol..... good luck=)

As a side note it was pointed out that the old switch was hard to unplug because it is glued in. To get the plug off use a heat gun, as soon as the glue starts to run it can be pulled apart without ruining either.

I just swapped from a MY 2002 4l60e with the old style plug to a MY 2007 4l80e with the new style plug. basically it looks like they just combined the range sensor and the solenoid sensor into one plug.

In my swap I only use the ground wire from the range sensor portion of the old plug, so I didn't trace out where the second pink was coming from or what purpose it served.

I suspect that you could piggyback it off the pink going to 11 on the new plug ( pin C on the old plug) and that it simply provides power to one of the range sensor functions (back up lights, etc)

to find out out for sure you'd have to look at a schematic for a MY 2005 or newer vehicle with a 4lxxe series tranny.

So I can splice the old plugs with the new one

Put the wires in the right places and it whould work, both diagrams are there so have at it.

Wtfchristal

most of the wires match up the only issue I have is the fact that there's 2 wires that don't match up. And the fact that one plug has 12 wires (but 2 of the pins aren't used) and the original plugs have 11 wires. Could I just swap out the whole neutral safety switch from the single connector and just use one that has 2?

Depends on what you are swapping the setup into, I try to use the N/S Switch that's factory to the vehicle.
