the wire that goes to the speedo in my cluster, i know the speedo wire from the computer thats running the motor/tranny(the 2004 computer). Chilton manuals only give you a hand full of wires in the schematic.Originally Posted by danger_ranger83

Yes its the right signal for the ecm. And you take the 4k output from the ecm and tie into a light blue with a black tracer wire for the speedo connection. The easiest place is behind the glove box where it comes out of the drac box.

Not sure what wire the 4k output is but is that going to be my green speedo wire from the lq4 computer? also can you explain the black tracer wire? i have a light blue/black wire from my white box.
Thanks bud
the 4k is just how the computer reads the signal from the VSS....i dont know anything about ur truck so i cant help u with the rest..sorry

Yeah the blue with a black stripe is the right one.

Right on thanks for the help i would see if it works but, I had to pull the motor, turns out the motor I bought has a spun bearing. So I'm currently looking for a short block or a cheap long block because I'm pretty sure the machine shop is going to charge at least 1500 bucks
Its been awhile, but the trucks been running, i ended up putting in a new lq9 and got rid of the garbage lq4 i bought. The truck runs great, pulls hard... all my gauges work besides my tach.
Ive got movement on my tach, it says it idles at 100 rpms and when im in the throttle it goes up to 1500 or so.
Right now ive got the tach wire from my new pcm to the wire to my factory tach. I got a 680ohm resistor 1/4 watt with a 12v switched power source. Anyone got any ideas of solutions? Thanks.
Out of curiosity, would your truck happen to be a 2004? NVM, just saw you have a 2004 engine/pcm. Damn, its such a pattern of issues, these damn 2004 PCMs and not able to drive a tachometer.

See my truck data in the "My Garage" section here... http://www.ls1truck.com/forums/my-ga...tml#post191709
Well it moves, I hope I don't have to go through a hundred resistors in order to find the right one
