4L60e Range Pinout

[66LSx]

Looking for a pinout schematic for the single large plug 4L60e range selector so I can accommodate reverse lights. My column was originally 3-on-the-tree but I will be utilizing it to shift the 4L60e

2004 5.3L / 4l60e 4x2

Here is my single plug switch...


Hope someone can help.... my PSI harness (never expected it too) did not come with a range selector plugin and tail off.... so need this for me backup lights... (and might even run the neutral safety switch too?)

I have no idea what direction each one is going... but I should be able to tone out now.....

Heres the info I found... not quite sure if the pink wires are 12V+ constant, or in the case of neutral safety.. 12+ Crank.... dunno yet.

There are no constant 12v wires to the range sensor, the pinks are 12v ignition power (key on).

I mean key on 12V vs crank 12V. (i shouldn't have said constant... my bad)

Crank = neutral safety switch
key on = reverse light supply voltage etc.

somewhere in there has to be an inhibit for a Neutral/Park using only crank voltage. (IE: Not in park, or N... no voltage to starter solenoid)

im unsure where your at. does your harness to pcm have a white wire to pin 34 on the blue connector?

maybe brendan's pin out for the 2004 harness pcm can help http://lt1swap.com/2004vortec_pcm.htm

[littlevictories]

oh, just read your harness has all the range stuff deleted.

man thats a good question. it could be 12+ , 12- or 5+

wish I had a stock 2004 harness to help ya

Yea if I had a new column.... I'd have a PNP & R light source built in.... but utilizing my 3-on-the-tree column... I do not.

[ls1nova71]

This seemed easier than trying to type it all out... You'll have a much more accurate NSS and back up lights using this sensor than the sloppy column mounted switch.

I re-read the schematic and second guessed my self, but after testing it I was right the first time. This would be the way to do it, so ignore the first drawing....

For the neutral lockout going to the additional relay before the starter solenoid... first image you used #9 (PNP Switch Signal)

The 2nd image you used #1 (Clutch Start Switch Signal)

Difference? (They may do the same thing)

PS: I owe you

[ls1nova71]

Not 100% sure, but checking it with a multi meter, only 1 and 12 had continuity in park and neutral. The other one may be for the shift interlock or something?

#1 it is....

I'll have a fusible link in between anyways so worst case scenario I cook a fuse, a PNP switch (which is stocked in the Autozone, Orielly etc), or a relay.

Looking forward to taking your diagram and getting a pig tail and going with it.... will multi meter and tone it also... and then bench test it before throwing it on.


I owe you a favor now.... (son of a....)

I'll have to check what I have for reverse lights too... (some of these old school bulbs can really draw) might have to put in another 87a for those also....

[littlevictories]

lemme know what ya do for the back up lights. I was gonna run 5 amp fuse in line and skip the relay...

Im doing a 2004 5.3 with a 4l60e in a 72 2wd k5
Can I remove all the pinouts from the PCM that go to range sensor and wire it like the diagram or does the PCM need to receive any sort of signal from it to indicate what gear its in
