Thank you Dave, I have seen the video, a lot of info, i am as well signed up to the facebook group and have posted my pinout chart their, in case someone will find them useful, but i haven`t seen the pictures and read the comment from the "1999-2002 4.8L, 5.3L, 6.0L Harness Re-Work Step by Step" that you have provided a link to, will study, a lot of helpful info their. Thank you
Hi Dave, i lied, that`s not the video i have seen, this one has all the info i need basically, thank you very much!!!
Few questions:
- Does anyone know how do i wire speedo from 0411 pcm wire that gives 4K output: via VSS Lo or VSS Hi wire, or both toghether?
Because the old type of speedo used to get the signal directly from the VSS sensor and transform it to 4k and then out of speedo to PCM/ECM as 4k pulses. But with the swap, the signal goes direct from sensor to PCM, PCM transforms it to 4k and out of the PCM. So where to wire it in the speedo, to wich wire/s???
- Another question is my VSS sensor is located on my transfer case NP241C, will it function correct with 0411, or will i have to change it if someone knows?
Thanks.

Ok, I found wiring scheme for speed signal DK_GRN wire coming out of C2 pin-50 connector of 0411 PCM.
But my main question is can i wire this DK_GRN wire coming out of C2 pin-50 directly to C100 Bulkhead (VSS Hi -Yellow wire) that used to get direct signal from VSS sensor twisted together with PPL wire Low range signal (that i just ground), and entered through Bulkhead C100 connector -> DRAC -> Speedo, or do i have overpass the DRAC and wire it directly to speedo?

Maybe it's possible to split / splice the VSS into two signals (4 wires)? Have two wires to the DRAC / VSSB to operate the Speedometer and have two wires for the '0411 PCM?
The DRAC / VSSB uses 40 Pulses Per Driveshaft Revolutions (PPR). The DRAC sends the speed signal to the speedometer.
The '0411 uses 40 Pulses Per Driveshaft Revolutions (PPR).

Hello Dave,Originally Posted by dave w
Thank you for reply,
Previously, before i got a new 1998 wiring, becouse the first one i got for free was all cut here and their, i tried splicing in in to the vss two screwed together wires ppl/wht&GRN/black, and connecting to Drac, and what happend is the speedo did not work and the 0411 did not see the vss. That is why i`m thinking of a solution, becouse this schem did not work unfortunately....
Got to find other solution, people say to wire the C50 GRN speed out of pcm wire to speedo directly passing the DRAC, but Cruise uses DRAC on older vehicles and abs as well, i wonder if these modules can use the C50 signal out of PCM as well...
If the DRAC sends 4k to Cruise, as the schem you have attached sayes, i can wire the it from C50 0411 speed signal, what wories me is that the speedo it says uses 2k at some vehicles..
Thank you.
Sincerely.
